Subject: macvlan: Set IFF_UNICAST_FLT flag to prevent unnecessary promisc mode.
From: Vlad Yasevich <vyasevic@xxxxxxxxxx>
[ 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.
