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. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
