Merge branch 'fix-bridge_vlan_aware-sh-and-bridge_vlan_unaware-sh-with-iff_unicast_flt'

Vladimir Oltean says:

====================
Fix bridge_vlan_aware.sh and bridge_vlan_unaware.sh with IFF_UNICAST_FLT

Make sure that h1 and h2 don't drop packets with a random MAC DA, which
otherwise confuses these selftests. Also, fix an incorrect error message
found during those failures.
====================
