From: Gregory Greenman <[email protected]> Statistics should be collected according to the actual rate a frame/aggregation was transmitted and not according to the initial rate from the last LQ command (these rates are different if the frames were retransmitted at a lower rate from the rate scale table).
This is needed to remove throughput degradation.
