Subject: wl12xx: Add support to RX packets payload alignment

In case of QoS packets the packet payload isn't aligned to
4 bytes. In that case the mac80211 layer take care of that
via memmove() in ieee80211_deliver_skb().
Add support of copy packets from aggregation buffer to the
skbs with packet payload aligned care. In case of QoS packets
copy the packets in offset of 2 bytes guarantee payload aligned
to 4 bytes.

Subject: wl12xx: remove rx filtering stuff

The new fw doesn't support rx_filtering configuration (as a
stand-alone command. the rx filtering is done automatically
according to the active role).

From 4d56ad9cae9e8553176427adc2335f8a7f4556b2 Mon Sep 17 00:00:00 2001
From: Eliad Peller <eliad@wizery.com>
Date: Sun, 14 Aug 2011 13:17:05 +0300
Subject: wl12xx: update fw status struct

Update the fw status struct according to the new fw api
(fw >= 6/7.0.0.35).
All the roles use the same struct now.

The memory accounting was changed a bit according to
the struct changes.
