Standard way would be to use macvlan

ip link add link eth0 name foo02 addr 44:44:44:44:00:02 type macvlan
ip link add link eth0 name foo03 addr 44:44:44:44:00:03 type macvlan

Or if you have a recent version of net-next you can add them directly
without using macvlan,

# bridge fdb add 44:44:44:44:00:02 dev eth0 self

But you'll need to wait a bit before that gets in a stable release.

I tried this, but this won't update the uc address and in netdev
struct  and won't call .ndo_set_multicast_list.

I am planning to use vlan through vconfig as below,

#vconfig add eth0 100
#ifconfig eth0.100 10.144.134.1 netmask 255.255.255.0 up
#ifconfig eth0.100 hw ether 00:55:22:44:f7:80

This will update uc in netdev and calls .ndo_set_multicast_list.

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
