Subject: macvlan: Only update pkt_type if destination MAC address matches
Patch-mainline: v4.15-rc1
Git-commit: c8c41ea1bd707eb032e248c55d640f32c950ed19
References: bsc#1109837
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.
