However, you could do that by having a net80211_ifattach() type thing that sets if_transmit and invokes the driver-provided if_start. I don't think wireless devices are using multiple transmit queues in such a way that if_transmit would be a benefit, and if_start is a simpler model. -- John Baldwin _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
