From 21fbbca3376f66edd010f5c76ea94e3353bf9a9e Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Wed, 30 Jan 2013 23:37:41 +0100 Subject: [PATCH] ath9k: report A-MPDU status The ath9k hardware reports whenever an frame was part of an A-MPDU. MAC80211 already provides the necessary API to pass this additional information along to whomever needs it. Signed-off-by: Christian Lamparter Signed-off-by: John W.
