Implement a separate hardware queue threshold for aggregate and non-aggr
traffic.
When transmitting non-aggregate traffic, we need to keep the hardware
busy whilst transmitting or small bursts in txdone/tx latency will
kill us.
This restores non-aggregate iperf performance, especially when doing
TDMA.
Tested:
* AR5416<->AR5416, TDMA
* AR5416 STA <-> AR9280 AP
