History
Adrian Chadd a40880ade4 Go back to direct-dispatch of the software queue and frame TX paths 
when they're being called from the TX completion handler.

Going (back) through the taskqueue is just adding extra locking and
latency to packet operations.  This improves performance a little bit
on most NICs.

It still hasn't restored the original performance of the AR5416 NIC
but the AR9160, AR9280 and later NICs behave very well with this.

Tested:

* AR5416 STA (still tops out at ~ 70mbit TCP, rather than 150mbit TCP..)
* AR9160 hostap (good for both TX and RX)
* AR9280 hostap (good for both TX and RX)
