On our hardware (050d:7050 Belkin Components F5D7050 Wireless G Adapter),
setting any WEP key with non zero index, cause rx frames corruption.

Note: perhaps (I did not check) this can be fixed differently - by using
hw_key_idx the same as true MAC key index. But according to the comment in
rt2x00mac_set_key():

"the hardware requires keys to be assigned in correct order (When key 1
is provided but key 0 is not, then the key is not found by the hardware
during RX)"

this will be quite problematic. Since WEP should not be used, disabling
hardware crypto offload for it will not hurt much. Beside static
one key WEP will still be offloaded.

The user ratekbs of MCS15 ShortGI is incorrect and can not be lesser
than MCS15 rate. This incorrect rate may affect switching to higher
rates as the rate control algorithm always finds MCS15 is better
than MCS15 ShortGI and results in lower throughput. Fix this by
feeding the correct user ratekbs for MCS15 ShortGI rate.

This issue affects 3 stream case very badly as the 3 stream rates are
not used at all once we scale down to MCS15 from 3 stream rates.

Key locking simplification removed key->sdata != NULL verification from
ieee80211_key_free(). While that is fine for most use cases, there is one
path where this function can be called with an unlinked key (i.e.,
key->sdata == NULL && key->local == NULL). This results in a NULL pointer
dereference with the current implementation. This is known to happen at
least with FT protocol when wpa_supplicant tries to configure the key
before association.

Avoid the issue by passing in the local pointer to
ieee80211_key_free(). In addition, do not clear the key from hw_accel
or debugfs if it has not yet been added. At least the hw_accel one could
trigger another NULL pointer dereference.

     rt2x00: Write the BSSID to register when interface is added

mananged mode in rt2500pci was broken, due to intf->bssid containing
random data rather then the expected 00:00:00:00:00:00

This is corrected by sending the BSSID to rt2x00lib_config_intf
only in AP mode where the bssid is set to a valid value.
