Merge branch 'xen-netback-next'
Zoltan Kiss says: ==================== xen-netback: Changes around carrier handling 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. ==================== Signed-off-by: Zoltan Kiss <zoltan.kiss@citrix.com> Signed-off-by: David Vrabel <david.vrabel@citrix.com> Signed-off-by: David S.
