From 2560b6e2e4b87df211ea39b3b02498959b70b4e8 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Thu, 10 Jul 2008 00:47:19 +0300 Subject: [PATCH] mac80211: Fix ieee80211_rx_reorder_ampdu: ignore QoS null packets This patch fixes the check at the entrance to ieee80211_rx_reorder_ampdu. This check has been broken by 'mac80211: rx.c use new helpers'. Letting QoS NULL packet in ieee80211_rx_reorder_ampdu led to packet loss in RX.
