of Adapters, version 4.4.x. This driver includes support for
of Adapters, version 5.0.x. This driver includes support for
Itanium(TM)-based systems.
This release version includes the following:
- Support for the ethtool 1.6 interface. A third-party application can use
the ethtool interface to get and set driver parameters.
- Zero copy. This feature provides faster data throughput. Enabled by
default in supporting kernels. It is not supported on the Intel(R)
PRO/1000 Gigabit Server Adapter.
Features include:
- Support for the 82545 and 82546-based adapters listed below
- Wake on LAN* support via ethtool for 82540, 82544, 82545, and 82546-
based adapters
- Adaptive IFS for increased performance at half duplex
Native VLANs are now available with supported kernels.

Valid Range: 100-100000 (0=off, 1=dynamic)
Default Value: 1
This value represents the maximum number of interrupts per second the
controller generates. InterruptThrottleRate is another setting used in
interrupt moderation. Dynamic mode uses a heuristic algorithm to adjust
InterruptThrottleRate based on the current traffic load.
NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
RxAbsIntDelay parameters. In other words, minimizing the receive
and/or transmit absolute delays does not force the controller to
generate more interrupts than what the Interrupt Throttle Rate
allows.

* o Implemented ethtool -S option
* o Strip /proc/net/PRO_LAN_Adapters files for kernel driver
* o Bug fix: Read wrong byte in EEPROM when offset is odd number
* o Bug fix: PHY loopback test fails on ICH devices
* o Bug fix: System panic on e100_close when repeating Hot Remove and
* Add in a team
* o Bug fix: Linux Bonding driver claims adapter's link loss because of
* not updating last_rx field
* o Bug fix: e100 does not check validity of MAC address
* o New feature: added ICH5 support
*
* 2.1.27 11/20/02
* o Bug fix: Device command timeout due to SMBus processing during init
* o Bug fix: Not setting/clearing I (Interrupt) bit in tcb correctly
* o Bug fix: Not using EEPROM WoL setting as default in ethtool

/* Change Log
*
* 4.4.19 11/27/02
* 5.0.43 3/5/03
* o Feature: Added support for 82541 and 82547 hardware.
* o Feature: Added support for Intel Gigabit PHY (IGP) and a variety of
* eeproms.
* o Feature: Added support for TCP Segmentation Offload (TSO).
* o Feature: Added MII ioctl.
* o Feature: Added support for statistics reporting through ethtool.
* o Cleanup: Removed proprietary hooks for ANS.
* o Cleanup: Miscellaneous code changes to improve CPU utilization.
* - Replaced "%" with conditionals and "+-" operators.
* - Implemented dynamic Interrupt Throttle Rate (ITR).
* - Reduced expensive PCI reads of ICR in interrupt.
* o Bug fix: Request IRQ after descriptor ring setup to avoid panic in
* shared interrupt instances.

* o Bug fix: Make ethtool EEPROM acceses work on older versions of ethtool.

* 4.4.12 10/15/02
* o Clean up: use members of pci_device rather than direct calls to

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.
Osamu Tomita : Separate driver for NEC PC-9800.

/* 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. */
