From c2368e795cec561229ef66a04ac51629b918a9e8 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Sun, 22 Aug 2010 17:35:32 +0000 Subject: [PATCH] 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.
