3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Veaceslav Falico <vfalico@xxxxxxxxxx>
[ Upstream commit 63134803a6369dcf7dddf7f0d5e37b9566b308d2 ]
dev->ndo_neigh_setup() might need some of the values of neigh_parms, so
populate them before calling it.
