Subject: [PATCH 08/10] wifi: remove orphaned wl3501 driver
From: Arnd Bergmann <arnd@...db.de>
Planet WL3501 is another PCMCIA driver for pre-802.11b interfaces
(2Mbit/s) with incomplete CFG80211 support.
This was marked as orphaned in 2017 but has been unmaintained
for a long time before that.

- * WL3501 Wireless LAN PCMCIA Card Driver for Linux
- * Written originally for Linux 2.0.30 by Fox Chen, mhchen@...f.ccl.itri.org.tw
- * Ported to 2.2, 2.4 & 2.5 by Arnaldo Carvalho de Melo <acme@...ectiva.com.br>
- * Wireless extensions in 2.4 by Gustavo Niemeyer <niemeyer@...ectiva.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)
