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