From 6e73611e574ea3c8fe5afc67ee29d2c5ff777f4b Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 11 Dec 2012 14:16:29 +0100 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.
