linux.git/drivers/net/ethernet/sun, branch v3.19 Linux kernel source tree sunvnet: set queue mapping when doing packet copies 2015-02-03T02:20:35+00:00 David L Stevens david.stevens@oracle.com 2015-01-30T17:29:45+00:00 44ba582beac4ff8e05a15e38548ebf3deb509547 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.
