   4 Subject: [PATCH 3/3] p54: zero-out rx_status
   5
   6 In commit 'mac80211: support radiotap vendor namespace RX data'
   7 new fields were added to 'struct ieee80211_rx_status'.
   8 The ath5k driver does not initializes those fields and
   9 this can cause unexpected behaviour. The patch ensures
  10 that each field gets initialized with zeroes.
