Subject[PATCH 005/104] neighbour: populate neigh_parms on alloc before calling ndo_neigh_setup
Date
3.8.13.11 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Veaceslav Falico <vfalico@redhat.com>

[ Upstream commit 63134803a6369dcf7dddf7f0d5e37b9566b308d2 ]

dev->ndo_neigh_setup() might need some of the values of neigh_parms, so
populate them before calling it.
