        src/sys/arch/xen/xen: if_xennet_xenbus.c

Log Message:
Stop using IFF_OACTIVE, just keep processing until we fill the Tx ring

xennet_tx_complete() is now called only in xennet_softstart() just
before processing Tx queue; xennet_handler() just schedules the
softint for xennet_softstart() iff the Tx ring list is completely empty

no performance changes observed

XXX the detach and suspend code expects xennet_handler() to collect
XXX the Tx responses, the tsleep() loop should still work since the tsleep()
XXX would allow the softint to trigger; untested though
