+Subject: [PATCH 1/3] 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.
+
+The rt2x00 driver from the compat-wireless-2012-12-01
+tarball caused the following warning:

+The patch ensures that each field gets initialized with
