From 8178d38b704f0a08a74b030c35e6eca5f5019d3d Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 18 Apr 2011 14:22:28 +0300 Subject: [PATCH] mac80211: allow low level drivers to report packet loss Add API that allows low level drivers to notify mac80211 about TX packet loss. This is useful when there are FW triggers to notify the low level driver about these events. Signed-off-by: Arik Nemtsov Signed-off-by: John W.
