* WL3501 Wireless LAN PCMCIA Card Driver for Linux |
|
* Written originally for Linux 2.0.30 by Fox Chen, [email protected] |
|
* Ported to 2.2, 2.4 & 2.5 by Arnaldo Carvalho de Melo <[email protected]> |
|
* Wireless extensions in 2.4 by Gustavo Niemeyer <[email protected]> |
|
* |
|
* 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) |
