d32a102819 mac80211: fix tx->skb NULL pointer dereference
In function ieee80211_tx_h_encrypt the var info was
initialized from tx->skb, since the fucntion
is called after the function ieee80211_tx_h_fragment
tx->skb is not valid anymore.

765cb46a3f mac80211: 802.11w - Add BIP (AES-128-CMAC)
Implement Broadcast/Multicast Integrity Protocol for management frame
protection. This patch adds the needed definitions for the new
information element (MMIE) and implementation for the new "encryption"
type (though, BIP is actually not encrypting data, it provides only
integrity protection). These routines will be used by a follow-on patch
that enables BIP for multicast/broadcast robust management frames.

5cf121c3cd mac80211: split ieee80211_txrx_data
Split it into ieee80211_tx_data and ieee80211_rx_data to clarify
usage/flag usage and remove the stupid union thing.

9ae54c8463 mac80211: split ieee80211_txrx_result
The _DROP result will need to be split in the RX path but not
in the TX path, so for preparation split up the type into two
types, one for RX and one for TX. Also make sure (via sparse)
that they cannot be confused.

6a22a59d48 [PATCH] mac80211: consolidate encryption
Currently we run through all crypto handlers for each transmitted
frame although we already know which one will be used. This
changes the code to invoke only the needed handler. It also moves
the wep code into wep.c.

4f0d18e26f [PATCH] mac80211: consolidate decryption
Currently, we run through all three crypto algorithms for each
received frame even though we have previously determined which
key we have and as such already know which algorithm will be
used. Change it to invoke only the needed function. Also move
the WEP decrypt handler to wep.c so that fewer functions need
to be non-static.
