Hello,
The last three MM kernels have fail to give me a working bcm43xx driver.
The odd thing is that dmesg output seems to indicate that the driver
is working okay. NetworkManager doesn't see the driver, though.
"iwlist scan" fails to find any access points, too. iwconfig shows
"Access Point: invalid".
I can confirm the symptoms, I see them too on my test boxes.
I tried backing out the following patches, and it fixes the problem:
drivers/net/wireless/bcm43xx/bcm43xx.h
drivers/net/wireless/bcm43xx/bcm43xx_main.c
drivers/net/wireless/bcm43xx/bcm43xx_power.c
drivers/net/wireless/bcm43xx/bcm43xx_wx.c
drivers/net/wireless/bcm43xx/bcm43xx_xmit.c
The missing patch is shown below. This patch was entitled "[PATCH] bcm43xx: Readd dropped
assignment" and submitted to wireless-2.6 by Daniel Drake on 10/17/06, but it seems to have fallen
through the cracks. It is a fix to a patch entitled "[PATCH] ieee80211: Move IV/ICV stripping into
ieee80211_rx" also submitted by Daniel Drake on 9/26/2006.
NOTE to maintainers: This problem affects BOTH wireless-2.6 and 2.6.19-rcX-mmY. At present, the
"Move IV/ICV" patch has not been incorporated into 2.6.19-rcX and it is OK.

In the patch sent by Daniel Drake under the title "[PATCH] ieee80211: Move
IV/ICV stripping into ieee80211_rx", a needed line was accidentally removed.
As my current copy of wireless-2.6.git does not contain this line, I am
(re)submitting a patch to restore that line.
