ar9170: xmit code revamp
This patch is a back-port from aggregation testing code.
In the past, we didn't limit the amount of active tx urbs.
However, ar9170 only has a limited buffer reserved for
pending data frames.
This wasn't much of a problem with the slower 802.11b/g.
We simply stopped the full queue and moved on to something different
in the mean time. But - as you guessed it - this simple approach
stands in way for a decent aggregation implementation.
