This driver should work with many programmed-I/O 8390-based ethernet
boards. Currently it supports the NE1000, NE2000, many clones,
and some Cabletron products.
Changelog:
Paul Gortmaker : use ENISR_RDC to monitor Tx PIO uploads, made
sanity checks and bad clone support optional.
Paul Gortmaker : new reset code, reset card after probe at boot.
Paul Gortmaker : multiple card support for module users.
Paul Gortmaker : Support for PCI ne2k clones, similar to lance.c
Paul Gortmaker : Allow users with bad cards to avoid full probe.
Paul Gortmaker : PCI probe changes, more PCI cards supported.
rjohnson@analogic.com : Changed init order so an interrupt will only
occur after memory is allocated for dev->priv. Deallocated memory
last in cleanup_modue()
Richard Guenther : Added support for ISAPnP cards
Paul Gortmaker : Discontinued PCI support - use ne2k-pci.c instead.

/* Probe for various non-shared-memory ethercards.
NEx000-clone boards have a Station Address PROM (SAPROM) in the packet
buffer memory space. NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of
the SAPROM, while other supposed NE2000 clones must be detected by their
SA prefix.
Reading the SAPROM from a word-wide card with the 8390 set in byte-wide
mode results in doubled values, which can be detected and compensated for.
The probe is also responsible for initializing the card and filling
in the 'dev' and 'ei_status' structures.
We use the minimum memory size for some ethercard product lines, iff we can't
distinguish models. You can increase the packet buffer size by setting
PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:
E1010 starts at 0x100 and ends at 0x2000.
E1010-x starts at 0x100 and ends at 0x8000. ("-x" means "more memory")
E2010 starts at 0x100 and ends at 0x4000.
E2010-x starts at 0x100 and ends at 0xffff. */

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

. A description of the SMSC registers is probably in order here,
. although for details, the SMC datasheet is invaluable.
.
. Basically, the chip has 4 banks of registers ( 0 to 3 ), which
. are accessed by writing a number into the BANK_SELECT register
. ( I also use a SMC_SELECT_BANK macro for this ).
.
. The banks are configured so that for most purposes, bank 2 is all
. that is needed for simple run time tasks.

This file contains the instructions, test methods, and caveats for the
smc91111.c driver. You may not be using the driver without reading this file.
Driver Description:
===================
This driver has been modified to work on kernel 2.4. And it also contains the
latest SMSC updates for the Odd Byte issue. Important thing to note about this
is that, this driver might not compile on kernel version older than 2.4.
Please visit the SMSC website (http://www.smsc.com) for latest updates on the
drivers.
Things to note about installation:
==================================
1. This is designed to be compiled and loaded as a module. While putting
it into your kernel should be possible, it has not yet been tested.
2. The driver will only load on recent kernels because of changes to
the network driver interface. I have compiled this under kernel 2.4.
3. To compile, run 'make' .
4. Loading the driver:
use: insmod smc91111.o
optional parameters:
io=0x### : your base address
irq=## : your irq
nowait=x : 0 for standard I/O access (IOCHRDY wait states)
1 for fast access (no IOCHRDY wait states)
5. To allow automatic loading and intialization of the driver at boot-up
add the following line to /etc/modules.conf (in RedHat 7.0):
alias eth0 smc91111
options eth0 io=0x### irq=##
See the man pages on module.conf. You must also be sure to copy the
smc91111.o file to the modules directory:
su
cd /lib/modules/YOUR_CURRENT_KERNEL_VERSION/net
cp 'directory where the file resides'/smc91111.o .
chown root:root smc91111.o
chmod a+r smc91111.o
Then you must update the module dependencies (as root):
/sbin/depmod
Advanced Features:
==================
If your Linux Kernel was compiled with the configuration options CONFIG_PROC_FS
and CONFIG_SYSCTL enabled then the smc91111 driver provides several sysctl
files for accessing extended features. These files can be found in
/proc/sys/dev/ethX, where X is the interface number of the ethernet port. For
example, if your SMC91C111 card is the only one in the system then your sysctl
files will be located at /proc/sys/dev/eth0.
The following lists the files supported by the driver.
sysctl file Description
------------- --------------------------------------------------------------
info Prints a list of supported files along with a terse
description of each one.
swver Prints the software version information of the driver.
autoneg When set to 1 enables auto negotiation mode. The LAN91C111
supports auto negotiation per IEEE 802.3 Clause 28. When auto
negotiation is set the files "rspeed" and "rfduplx" (below)
limit what capabilities are broadcast to the remote end.
When "autoneg" is set to 0 the auto-negotiation feature
is disabled, and the speed and duplex can be controlled
directly and immediately with "rspeed" and "rfduplx".
You can change the value of this file by issuing the command
"echo 0 > autoneg", assuming that you are in the directory
/proc/sys/dev/ethX.
The default value of "autoneg" is 1.
aspeed Reports the actual speed of the link. This file is read-only.
afduplx Reports the actual duplex of the link. A value of 1 indicates
the link is currently operating in full duplex. This file
is read-only.
rspeed Requested speed, controls the speed of the interface. The
behavior invoked by this file depends on the value of
the "autoneg" file. See the "autoneg" description above. A value
of 100 indicates 100Mpbs, and a speed of 10 indicates 10Mbps.
You cannot change the value of "rspeed" when "autoneg" is
set to 1. You can issue the following commands to restrict
the LAN91C111 to 10Mbps operation:
cd /proc/sys/dev/eth0
echo 0 > autoneg
echo 10 > speed
echo 1 > autoneg
The default value of "speed" is 100.
rfduplx Requested duplex, controls the duplex operation of the
interface. The behavior invoked by this file depends on the
value of the "autoneg" file. See the "autoneg" description
above. A value of 1 indicates full duplex, while a value of 0
indicates half duplex operation. You cannot change the value
of "rfduplx" when "autoneg" is set to 1. The default value of
"rfduplx" is 1.
lnkfail When 1 indicates the PHY link is in a failure state (i.e.
not connected to a valid LAN). A value of 0 indicates
normal operation.
miiop When set to 1 selects an external PHY. This feature has not
yet been tested. The default value of "miiop" is 0.
swfdup When set to 1 enables Switched Full Duplex Operation. This
is to be used only when miiop is set to 1 (according to the
LAN91C111 documentation). This feature has not yet been
tested. The default value of "swfdup" is 0.
ephloop When set to 1 enables a loopback in the EPH block. This feature
has not yet been tested. The default value of "ephloop" is 0.
forcol When set to 1 forces a collision. This feature has not yet been
tested. The default value of "forcol" is 0.
filtcar When set to 1 the LAN91C111 filters the leading edge of carrier
sense for 12 bit times. This feature has not yet been tested.
The default value of "filtcar" is 0.
freemem Reports the amount of buffer memory currently free, in bytes.
totmem Reports the total amount of buffer memory contained in the
LAN91C111, in bytes.
leda Reports and controls which line condition is reported on
LEDA. I tested this feature with the SMSC EVB111-ISA board.
LED A on this card is green and is labelled "100". This
file accepts values from 0 thru 7.
Value Line Condition Reported
----- ----------------------------------------------
0 Logical OR of 100Mbps and 10Mbps link detected
1 Reserved
2 10Mpbs link detected
3 Full Duplex Mode Enabled
4 Transmit or Receive packet occurred
5 100Mbps Link Detected
6 Transmit packet occurred
7 Receive packet occurred
The default value of "leda" is 5.
ledb Reports and controls which line condition is reported on
LEDB. I tested this feature with the SMSC EVB111-ISA board.
LED B on this card is yellow and is labelled "FD". This
file accepts values from 0 thru 7 (see above).
The default value of "ledb" is 3.
chiprev Reports the chip revision number of the LAN91C111.
Testing Methodology and Report:
===============================
I tested the smc91111.c driver using RedHat 7.1. The version I tested with
came with kernel version 2.4.2. I updated the gcc tools because of
known bugs in this version of the RedHat distribution. It should not have
made a difference though, as the module is actually compiled using the "kgcc"
compiler provided by RedHat 7.1 (you have to manually install the kgcc rpm
from the CDROM).
I used two machines to perform tests. The first is an AST Bravo MS-T PRO 6200,
Model 2500C. It contains a PentiumPro w/integrated 256KB L2 cache, 64Mbytes of
EDO DRAM, and a 2.5GB EIDE hard drive.
The second machine is a generic Pentium II running at 360MHz. It contains
64Mbytes of SDRAM, and a 30GB hard drive. I used a NetGear FA311 PCI Ethernet
card in this machine. I compiled and installed the fa311.c driver provided
with the card.
I tested in two configurations. The first was in isolation, where the two
machines were connected to each other with a CAT5 crossover cable. The second
configuration connected both machines to a local area network running at
10Mbps. This lan containes three Windows machines and an Efficient Networks
SpeedStream router, connected to the Internet through an IDSL (today it is
served by Northpoint, tomorrow it is serviced by ????)
Test Scenerio #1
Testing in Isolated Network
The PentiumPro machine with the EVB111-ISA card is named "LOCAL", with IP address 216.36.95.135, netmask 255.255.255.240.
The PentiumII machine with the NetGear FA311 is named "REMOTE", with IP address of 216.36.95.134, netmask 255.255.255.240.
1. Bring the interface up.
The insmod and ifconfig programs must be executed as root.
LOCAL: /sbin/insmod smc91111.o
Check /var/log/messages (at end) for results. You should see the I/O address
and IRQ assigned to the card by the auto probe function.
LOCAL: /sbin/ifconfig eth0 216.36.95.135 netmask 255.255.255.240
Verify that the interace is up by checking the results of ifconfig:
LOCAL: /sbin/ifconfig
Verify that the Ethernet MAC address reported by ifconfig looks reasonable.
The card I tested with contained the address "00:80:0F:6A:00:00". Beware
of addresses with all zeros, all ones, or repeating bytes.
Test Result: Passed
