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
|
|
zeroes.
