From 5110effee8fde2edfacac9cd12a9960ab2dc39ea Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 2 Jul 2012 02:21:03 -0700 Subject: net: Do delayed neigh confirmation. When a dst_confirm() happens, mark the confirmation as pending in the dst. Then on the next packet out, when we have the neigh in-hand, do the update. This removes the dependency in dst_confirm() of dst's having an attached neigh. While we're here, remove the explicit 'dst' NULL check, all except 2 or 3 call sites ensure it's not NULL. So just fix those cases up. Signed-off-by: David S.
