From 7546dd97d27306d939c13e03318aae695badaa88 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 9 Mar 2009 08:18:29 +0000 Subject: net: convert usage of packet_type to read_mostly Protocols that use packet_type can be __read_mostly section for better locality. Elminate any unnecessary initializations of NULL. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
