Subject: [PATCH 1/3] rt2x00: zero-out rx_status
Subject: [PATCH v2] rt2x00: zero-out rx_status
In commit 'mac80211: support radiotap vendor namespace RX data'
new fields were added to 'struct ieee80211_rx_status'.
The rt2x00 driver does not initializes those fields and
this can cause unexpected behaviour.
new fields were added to 'struct ieee80211_rx_status' and those
fileds must be zeroed. However the rt2x00 driver stores driver
specific data in the cb array of the rx skbs, so the fields
might contain garbage and this can cause unexpected behaviour.
The rt2x00 driver from the compat-wireless-2012-12-01
tarball caused the following warning:

new fields were added to 'struct ieee80211_rx_status'.
The ath5k driver does not initializes those fields and
