It improves the performance for those speeds. And, there -is no effect for the other speeds. - -For 10M/half and 100M/half, the fast inter frame gap time let the -device couldn't use the feature of the aggregation effectively, -because the transfer would be completed fastly. Therefore, use the -maximum value to improve the effect of the aggregation.
