df1404650c mac80211: remove support for IFF_PROMISC
This support is essentially useless as typically networks are encrypted,
frames will be filtered by hardware, and rate scaling will be done with
the intended recipient in mind. For real monitoring of the network, the
monitor mode support should be used instead.

Removing it removes a lot of corner cases.

c678de5536 at76c50x: fix scan does not work with latest mac80211
since commit 3afc2167f6 scan in not
working anymore, due to mac80211 requires rx frequency status
information.

This patch makes the driver report this information.

While NOT scanning this is straightforward.
While scanning the firmware performs RF sweep and we cannot track
the actual tuning frequency, so this is guessed by parsing beacons
and probe responses.
This should be enough for ensuring functionality.

Thanks-to: Johannes Berg <johannes@sipsolutions.net> [ for suggestions and reviewing ]

347f8fdb61 at76c50x-usb: Make WEP encryption working.
Currently the driver uses HW encryption.
Whenever mac80211 calls the set_key() callback the driver restarts the
whole HW configuration procedure, in order to set (also) the new
WEP key.
However, by doing this, it causes the card to loose association information,
and the HW becomes unable to communicate with the BSS.

This patch adds support for sending another HW command, that sets only
the wep key, instead of resetting all.
Mac80211 key-set requests are thus handled via this new command.

Tested on my at76c503

a185045c8d at76c50x-usb: Extract bssid from authentication frame
The driver at76c50x-usb is unable to authenticate with an AP since
kernel 2.6.31 for the following reason: The join command of the firmware
needs to be sent with the right bssid before any transmission can start.
Before kernel 2.6.31 mac80211 informed its drivers about the changing
bssid early enough for at76c50x-usb but during the development of 2.6.31
mac80211's behaviour changed. Now a new bssid is set after the
association.

This patch changes the tx routine of the driver at76c50x-usb in such a
way that a new bssid is extracted from an authentication frame and the
join command with that bssid is processed.
