Date: Mon, 4 Aug 2014 16:20:56 +0100 From: Zoltan Kiss <zoltan.kiss@...rix.com> To: Wei Liu <wei.liu2@...rix.com>, Ian Campbell <Ian.Campbell@...rix.com> CC: Zoltan Kiss <zoltan.kiss@...rix.com>, David Vrabel <david.vrabel@...rix.com>, <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <xen-devel@...ts.xenproject.org> Subject: [PATCH net-next 0/2] 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.
