I should have spotted this before.

For slow CPU, the frequent bulk transfer would cause poor throughput.
One solution is to increase the timeout of the aggregation. It let
the hw could complete the bulk transfer later and fill more packets
into the buffer. Besides, it could reduce the frequency of the bulk
transfer efficiently and i
