This series starts using carrier off as a way to purge packets when the guest is not able (or willing) to receive them. It is a much faster way to get rid of packets waiting for an overwhelmed guest. The first patch changes current netback code where it relies currently on netif_carrier_ok. The second turns off the carrier if the guest times out on a queue, and only turn it on again if that queue (or queues) resurrects.
