From d063ed0f0cd623b45edc6f4781dda6478c56bb4f Mon Sep 17 00:00:00 2001 From: Vivek Natarajan Date: Tue, 23 Dec 2008 18:17:19 -0800 Subject: [PATCH] mac80211: Reset the power save timer from master_start_xmit. When a null data frame is generated from mac80211, it goes through master_start_xmit and not through subif_start_xmit. Hence for the power save timer to be triggered while sending this null data frame also, the timer has to be reset from master_start_xmit. Signed-off-by: Vivek Natarajan Signed-off-by: John W.
