Subject: [PATCH net] sunvnet: set queue mapping when doing packet copies
Date: Thu, 29 Jan 2015 11:46:30 -0500	[thread overview]
Message-ID: <54CA63E6.3020603@oracle.com> (raw)
In-Reply-To: <54C90AED.7040404@oracle.com>


[resending this since it never appeared on netdev yesterday]

This patch fixes a bug where vnet_skb_shape() didn't set the already-selected
 queue mapping when a packet copy was required. This results in using the
 wrong queue index for stops/starts, hung tx queues and watchdog timeouts
 under heavy load.
