Currently the aggregation is formed till the aggregation limit
is reached and the rate lookup is done for the first frame alone.
But there can be a legacy rated frames in tid queue. This patch
limits the subframe addition based on presence of legacy rate and
sends the legacy rated frames as unaggregated one.
