9ae4fda332 mac80211: allows driver to request a Phase 1 RX key
This patch makes mac80211 able to send a phase1 key for TKIP
decryption.
This is needed for drivers that don't do the rekeying by themselves
(i.e. iwlwifi). Upon IV16 wrap around, the packet is decrypted in SW,
if decryption is ok, mac80211 calls to update_tkip_key  with a new
phase 1 RX key.

5d2cdcd4e8 mac80211: get a TKIP phase key from skb
This patch makes mac80211 able to compute a TKIP key from an skb.
The requested key can be a phase 1 or a phase 2 key.
This is useful for drivers who need to provide tkip key to their
HW to enable HW encryption.

17e476b8db iwlwifi-2.6: RX status translation to old scheme
This patch adds translation for the RX status of an incoming packet.
The incoming status has to be translated to the old scheme in order to know
if the decryption has been done, MIC failure has occured, TTAK is valid etc...
This translation is mandatory for all RX packets when using 5300 and for
all HT packets using 4965.

c49c3b77c8 libertas: convert GET_LOG to a direct command
Now uses __lbs_cmd() to get the "log" (it's actually more a snapshot of
various counters, not a sequential log). Besides the "mechanical" convertion
the patch add the following logical changes:

* Removes the priv->logmsg variable, it was only used in one place anyway,
  also don't blindly get the counters when associating. Getting the
  counters then the user asks via WEXT for them is good enought.
* don't set wstats.discard.fragment with log.rxfrag, because the latter is
  a counter for successfully received packets, not for fragmented packets.

noop. Just setting the callback argument to __lbs_cmd_async()

If we loop more than once in gem_poll(), we'll
use more than the real budget in our gem_rx()
