  NAT64 is treated as a modify header action. The action order and
limitation should be the same as that of modify header in each
domain.

Since the last 2 TAG registers will be used implicitly in the
address backup mode, the values in these registers are no longer
valid after the NAT64 action. The application should not try to
match these TAGs after the rule that contains NAT64 action.
