From 1fb9489bf190ce2b3fc03891f3de4b2d30600e28 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 8 Aug 2012 21:53:36 +0000 Subject: net: Loopback ifindex is constant now As pointed out, there are places, that access net->loopback_dev->ifindex and after ifindex generation is made per-net this value becomes constant equals 1. So go ahead and introduce the LOOPBACK_IFINDEX constant and use it where appropriate. Signed-off-by: Pavel Emelyanov Acked-by: Eric Dumazet Signed-off-by: David S.
