3.5.7.9 -stable review patch.  If anyone has any objections, please let me know.

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

From: Vlad Yasevich <vyasevic@redhat.com>

commit 87ab7f6f2874f1115817e394a7ed2dea1c72549e upstream.

Macvlan already supports hw address filters.  Set the IFF_UNICAST_FLT
so that it doesn't needlesly enter PROMISC mode when macvlans are
stacked.
