back to normal (tx are transmitted). One may have to unload rt2800pci
and reload it to free the queue which are full though to see tx working.

I tried this patch with a rt2860 pci chipset and ifconfig wlan2 up
just returns : Unknown error 132...
Before this patch, iwlist wlan2 scan was working well.
I'm trying to learn rt2800pci as fast as I can, but I'm not yet in a
position to comment your code.

Benoit
