This should work macvlan calls uc_sync and mc_sync on the lowerdev. It
is working on the tip at least,

# bridge fdb show dev p3p2
01:00:5e:00:00:01 self permanent
33:33:00:00:00:01 self permanent
33:33:ff:69:9f:09 self permanent
# ip link add link p3p2 address 00:11:22:33:44:55 type macvlan
# ip link set dev macvlan0 up
# bridge fdb show dev p3p2
00:11:22:33:44:55 self permanent
01:00:5e:00:00:01 self permanent
33:33:00:00:00:01 self permanent
33:33:ff:69:9f:09 self permanent
33:33:ff:33:44:55 self permanent
