Public bug reported:
port's allowed_address_pairs allow different IP and MAC set for port.
The current ovsfw implementation has this issue for allowed_address_pairs with
different MAC with VM's MAC:
1. Packets with allowed_address_pairs' MAC and IP (different MAC with VM's MAC)
cannot come out from VM because the table=72 OpenFlow only check dl_src=VM-MAC
in br-int.
2. Cannot ping from outside to VM's allowed_address_pairs' MAC and IP
(different MAC with VM's MAC) because the table=0 OpenFlow only check
dl_dst=VM-MAC.
We need to allow the situation that address_pairs with different MAC
with VM's MAC.
Suggest change:
1. Do not check dl_src in table=72 because table=72 has checked dl_src for
Egress
2. Add all allowed MACs in table=0 and table=73 for Ingress
3. Check dl_dst and nw_dst in table=81 like table=71 do
4. Do not check dl_dst in table=82 because this check has done in table=0 and
table=73
