MAC address in allowed_address_pairs is unreachable in OVN

[Han Zhou]

Currently allowed_address_pairs works only if the mac in the allowed address pair is the same as the mac address of the port (ip can be different). Otherwise, packets destined to the new mac address cannot be delivered to the port, because there is no logical flow in L2 lookup stage in OVN for the new mac. The solution could be adding the new mac to "addresses" of the OVN lport.

    Add mac from allowed_address_pairs to ovn lport addresses

    Currently allowed_address_pairs works only if the mac in the allowed
    address pair is the same as the mac address of the port (ip can be
    different). Otherwise, packets destined to the new mac address
    cannot be delivered to the port, because there is no logical flow
    in L2 lookup stage in OVN for the new mac. This patch fixes it by
    adding the new mac to "addresses" of the OVN lport.
