Add MAC address check in ethernet-input node if interface in L3 mode

Browse Source 
Interface can be in promiscuous mode if more than one of its sub-
interface is in L2 mode. In promiscuous mode, L3 interface need to
verify DMAC of packet to match that of the interface and drop if not.
This check was done on sub-interface only and now also added to main
interface path.

Fix incorrect MAC addresses in the flow-per-pkt plugin test, which
caused it to fail.

Fix MAC address usage in BFD tests.
