3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Vlad Yasevich <vyase...@redhat.com>
[ Upstream commit 87ab7f6f2874f1115817e394a7ed2dea1c72549e ]
Macvlan already supports hw address filters. Set the IFF_UNICAST_FLT
so that it doesn't needlesly enter PROMISC mode when macvlans are
stacked.
