		1. One dnlink BK (18Mbps), Two uplinks BE (18Mbps) and BK (22Mbps)
			When we do aggregation for BK traffic, there will have many NAKs
			from USB device, only one pipe for Synopsys host controller,
			these NAKs will cause we can not receive all packets from uplinks.

			And the throughput of uplink BE will be smaller than dnlink BK.

			Solution: No aggregation for dnlink in the case.

		2. Two dnlink BE (18Mbps) and BK (22Mbps), one uplink BK (18Mbps)
			We need to use aggregation function to get higher throughput for
			BE traffic.

		So some cases need aggregation and some cases do not need it.

		==> Final solution:

		1. Only for 20MHz and no BLOCK ACK mechanism in RT3052 platform.

		2. Check how many ACs are used before aggregation.
			If only one AC is used, aggregation function is disabled.
			If more than one AC are used, aggregation function is enabled.
