LP PHY Dell device not working properly with b43 even in PIO mode

[Anisse Astier]

Hi,

Running John Linville's wireless-next tree(HEAD:
6d1d4ea4a82f8c17a3ff7c2f677bc3d41ea7484b), I have troubles with a
Broadcom wireless card that can't properly connect. This device is also
managed by wl, that supports it more or less properly (at least without
crashing). AFAIK, the card isn't supported by brcm80211.

It can connect, and even get an IP, but after some time it will just stop
working until reboot. The AP uses WPA2-PSK/TKIP.


The device:
0e:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
	Subsystem: Dell Wireless 1397 WLAN Mini-Card [1028:000c]

The log (I have similar problems if I load it directly in PIO mode) :
