* - 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
* Shmulik Hen <shmulik.hen at intel dot com>
* - Moved setting the slave's mac address and openning it, from
* the application to the driver. This enables support of modes
* that need to use the unique mac address of each slave.
* The driver also takes care of closing the slave and restoring its
* original mac address upon release.
* In addition, block possibility of enslaving before the master is up.
* This prevents putting the system in an undefined state.
*
* - 2003/05/01 - Amir Noam <amir.noam at intel dot com>
* - Added ABI version control to restore compatibility between
* new/old ifenslave and new/old bonding.
* - Prevent adding an adapter that is already a slave.
* Fixes the problem of stalling the transmission and leaving
* the slave in a down state.
*
* - 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
* - Prevent enslaving if the bond device is down.
* Fixes the problem of leaving the system in unstable state and
* halting when trying to remove the module.
* - Close socket on all abnormal exists.
* - Add versioning scheme that follows that of the bonding driver.
* current version is 1.0.0 as a base line.
*
* - 2003/05/22 - Jay Vosburgh <fubar at us dot ibm dot com>
* - ifenslave -c was broken; it's now fixed
* - Fixed problem with routes vanishing from master during enslave
* processing.
*
* - 2003/05/27 - Amir Noam <amir.noam at intel dot com>
* - Fix backward compatibility issues:
* For drivers not using ABI versions, slave was set down while
* it should be left up before enslaving.
* Also, master was not set down and the default set_mac_address()
* would fail and generate an error message in the system log.
* - For opt_c: slave should not be set to the master's setting
* while it is running. It was already set during enslave. To
* simplify things, it is now handeled separately.

* WL3501 Wireless LAN PCMCIA Card Driver for Linux
* Written originally for Linux 2.0.30 by Fox Chen, mhchen@golf.ccl.itri.org.tw
* Ported to 2.2, 2.4 & 2.5 by Arnaldo Carvalho de Melo <acme@conectiva.com.br>
* Wireless extensions in 2.4 by Gustavo Niemeyer <niemeyer@conectiva.com>
*
* References used by Fox Chen while writing the original driver for 2.0.30:
*
* 1. WL24xx packet drivers (tooasm.asm)
* 2. Access Point Firmware Interface Specification for IEEE 802.11 SUTRO
* 3. IEEE 802.11
* 4. Linux network driver (/usr/src/linux/drivers/net)
* 5. ISA card driver - wl24.c
* 6. Linux PCMCIA skeleton driver - skeleton.c
* 7. Linux PCMCIA 3c589 network driver - 3c589_cs.c
*
* Tested with WL2400 firmware 1.2, Linux 2.0.30, and pcmcia-cs-2.9.12
* 1. Performance: about 165 Kbytes/sec in TCP/IP with Ad-Hoc mode.
* rsh 192.168.1.3 "dd if=/dev/zero bs=1k count=1000" > /dev/null
* (Specification 2M bits/sec. is about 250 Kbytes/sec., but we must deduct
* ETHER/IP/UDP/TCP header, and acknowledgement overhead)
*
* Tested with Planet AP in 2.4.17, 184 Kbytes/s in UDP in Infrastructure mode,
* 173 Kbytes/s in TCP.
*
* Tested with Planet AP in 2.5.73-bk, 216 Kbytes/s in Infrastructure mode
* with a SMP machine (dual pentium 100), using pktgen, 432 pps (pkt_size = 60)
