Addrtype match has a new revision (1), which lets address type checking limited to the interface the current packet belongs to. Either incoming or outgoing interface can be used depending on the current hook. In the FORWARD hook two maches should be used if both interfaces have to be checked. The new structure is ipt_addrtype_info_v1. Revision 0 lets older userspace programs use the match as earlier. ipt_addrtype_info is used.
