X-Git-Tag: firefly_0821_release~7613^2~3670^2~722 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c2368e795cec561229ef66a04ac51629b918a9e8;p=firefly-linux-kernel-4.4.55.git bridge: is PACKET_LOOPBACK unlikely()? While looking at using netdev_rx_handler_register for openvswitch Jesse Gross suggested that an unlikely() might be worthwhile in that code. I'm interested to see if its appropriate for the bridge code. Cc: Jesse Gross Signed-off-by: Simon Horman Signed-off-by: David S.
