2 * WL3501 Wireless LAN PCMCIA Card Driver for Linux
3 * Written originally for Linux 2.0.30 by Fox Chen, mhchen@golf.ccl.itri.org.tw
4 * Ported to 2.2, 2.4 & 2.5 by Arnaldo Carvalho de Melo <acme@conectiva.com.br>
5 * Wireless extensions in 2.4 by Gustavo Niemeyer <niemeyer@conectiva.com>
7 * References used by Fox Chen while writing the original driver for 2.0.30:
9 * 1. WL24xx packet drivers (tooasm.asm)
10 * 2. Access Point Firmware Interface Specification for IEEE 802.11 SUTRO
12 * 4. Linux network driver (/usr/src/linux/drivers/net)
13 * 5. ISA card driver - wl24.c
14 * 6. Linux PCMCIA skeleton driver - skeleton.c
15 * 7. Linux PCMCIA 3c589 network driver - 3c589_cs.c
17 * Tested with WL2400 firmware 1.2, Linux 2.0.30, and pcmcia-cs-2.9.12
18 * 1. Performance: about 165 Kbytes/sec in TCP/IP with Ad-Hoc mode.
19 * rsh 192.168.1.3 "dd if=/dev/zero bs=1k count=1000" > /dev/null
20 * (Specification 2M bits/sec. is about 250 Kbytes/sec., but we must deduct
21 * ETHER/IP/UDP/TCP header, and acknowledgement overhead)
23 * Tested with Planet AP in 2.4.17, 184 Kbytes/s in UDP in Infrastructure mode,
24 * 173 Kbytes/s in TCP.
26 * Tested with Planet AP in 2.5.73-bk, 216 Kbytes/s in Infrastructure mode
27 * with a SMP machine (dual pentium 100), using pktgen, 432 pps (pkt_size = 60)
