I also have seen one of these for some time.

With the commit reverted, the latest kernel-wireless version works.

Just to be clear, b43 is used as a station, not as AP. The card I am using has a
G PHY. I added printk statements for every setting of 'authorized' in
net/mac80211/tx.c. It is set false at line 1984, thus 'multicast' is false.
Furthermore, sta is not NULL, but WLAN_STA_AUTHORIZED is not set in the sta
flags. Note: sta->_flags is 0x60023.
Although sdata->vif.type is set to 2 (NL80211_IFTYPE_STATION), variable
'authorized' was not touched at line 1908, thus "sdata->wdev.wiphy->flags &
WIPHY_FLAG_SUPPORTS_TDLS" is false. The content of sdata->wdev.wiphy->flags is
0x1401f8.

I'm running openSUSE 12.3 RC1, which has version 1.1 of wpa_supplicant. The
router is a Netgear WNDR3300 running standard firmware and set for WPA2-PSK(AES)
encryption.
Checking with newer versions of the supplicant is being a problem. I built both
2.0 from the tarball and 2.1-devel from the git repo, but nether will run with
NetworkManager. I will see if I can resolve that problem later.
Thanks,
Larry
