-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' 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:
