From e6306b1482b395e64a42e187435c53d79a5cecc3 Mon Sep 17 00:00:00 2001 From: Luis R. Rodriguez Date: Wed, 23 Dec 2009 16:29:49 -0800 Subject: [PATCH 5/5] ath9k: wake hardware during AMPDU TX actions This is a port of upstream commit: AMDPDU actions poke hardware for TX operation, as such we want to turn hardware on for these actions. AMDPU RX operations do not require hardware on as nothing is done in hardware for those actions. Without this we cannot guarantee hardware has been programmed correctly for each AMPDU TX action.
