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> | |
6 | * | |
7 | * References used by Fox Chen while writing the original driver for 2.0.30: | |
8 | * | |
9 | * 1. WL24xx packet drivers (tooasm.asm) | |
10 | * 2. Access Point Firmware Interface Specification for IEEE 802.11 SUTRO | |
11 | * 3. IEEE 802.11 | |
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 | |
16 | * | |
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) | |
22 | * | |
23 | * Tested with Planet AP in 2.4.17, 184 Kbytes/s in UDP in Infrastructure mode, | |
24 | * 173 Kbytes/s in TCP. | |
25 | * | |
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) | |
