iwlwifi: mvm: set A-MPDU bit upon empty BA notification from FW
The bit was set only if there was at least one reclaimed frame in an aggregation. It's important to set it also in the case that the whole A-MPDU was lost, otherwise rate scaling statistics will not be updated correctly. Thus, set it always in ba notification handler. This fixes a throughput degradation of about 20% in certain scenarios with multiple streams on 11ac. Signed-off-by:Gregory Greenman <gregory.greenman@intel.com> Signed-off-by:
