Subject: [PATCH] macvlan: Set IFF_UNICAST_FLT flag to prevent unnecessary promisc mode.
Date: Thu, 7 Mar 2013 15:21:48 -0500 [thread overview]
Message-ID: <1362687708-8685-1-git-send-email-vyasevic@redhat.com> (raw)
Macvlan already supports hw address filters. Set the IFF_UNICAST_FLT
so that it doesn't needlesly enter PROMISC mode when macvlans are
stacked.
