From 65ac6a5fa658b90f1be700c55e7cd72e4611015d Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Wed, 20 Oct 2010 13:56:05 +0000 Subject: vlan: Avoid hash table lookup to find group. A struct net_device always maps to zero or one vlan groups and we always know the device when we are looking up a group. We currently do a hash table lookup on the device to find the group but it is much simpler to just store a pointer. Signed-off-by: Jesse Gross Signed-off-by: David S.
