From 4c0faf816beeb5d4175cff09c96e668a49ad032f Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 11 Dec 2012 14:16:15 +0100 Subject: [PATCH 2/3] ath5k: 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.
