Even with moving netif_tx_disable() to an earlier point when taking down the queues for a reconfiguration, we still end up with the occasional netdev watchdog Tx Timeout complaint. The old method of using netif_trans_update() works fine for queue 0, but has no effect on the remaining queues. Using netif_device_detach() allows us to signal to the watchdog to ignore us for the moment.
