This allows user-space monitoring of BSS parameters for the associated
station. This is useful for debugging and verifying that the paramaters
are as expected.

The only thing that using crypto_blkcipher with ecb does over just using
arc4 directly is wrapping the encrypt/decrypt function into a for loop,
looping over each individual character.
To be able to do this, it pulls in around 40 kb worth of unnecessary
kernel modules (at least on a MIPS embedded device).
Using arc4 directly not only eliminates those dependencies, it also makes
the code smaller.

The commit "mac80211: reply to directed probes in IBSS" changed ad-hoc
specific code to respond to unicast probe requests, even if
drv_tx_last_beacon returns false, however due to confusion over the
meaning of the IEEE80211_RX_RA_MATCH flag, it also unconditionally
enabled responding to multicast probe requests.
Fix this by explicitly checking for a multicast destination address
instead.

ieee80211_tx_status iterates over all tx rates the driver reports back
in order to
1) mark tx rates as invalid if the driver cannot have tried that rate
2) find the actually used tx rate for the final retransmission
By leaving the for loop when the first invalid rate index is found we
can move the rates_idx assignment after the loop and therefore save
a few assignments and conditionals.
