Subject: [net-next PATCH 2/2] macvlan: Only update pkt_type if destination
 MAC address matches

From: Alexander Duyck <alexander.h.duyck@...el.com>

This patch updates the pkt_type to PACKET_HOST only if the destination MAC
address matches on the on the source based macvlan. It didn't make sense to
be updating broadcast, multicast, and non-local destined frames with
PACKET_HOST.
