History
adrian a6f6f69850 if_arge has had a strange bug that only appears during high traffic 
levels. TX would hang, RX wouldn't. A bit of digging showed the interface
send queue was full, but IFF_DRV_OACTIVE was clear and the hardware TX
queue was empty.

It turns out that there wasn't a check to drain the interface send
queue once hardware TX had completed, so if the interface send queue
had filled up in the meantime, subsequent packets would be dropped
by the higher layers and if_start (and thus arge_start()) would never
be called.

The fix is simple - call arge_start_locked() in the software interrupt
handler after the hardware TX queue has been handled or a TX underrun
occured. This way the interface send queue gets drained.
