o Modify ipfw(8) to be able set any prefix6 not just Well-Known, and also show configured prefix6; o relocate some definitions and macros into proper place; o convert nat64_debug and nat64_allow_private variables to be VNET-compatible; o add struct nat64_config that keeps generic configuration needed to NAT64 code; o add nat64_check_prefix6() function to check validness of specified by user IPv6 prefix according to RFC6052; o use nat64_check_private_ip4() and nat64_embed_ip4() functions instead of nat64_get_ip4() and nat64_set_ip4() macros. This allows to use any configured IPv6 prefixes that are allowed by RFC6052; o introduce NAT64_WKPFX flag, that is set when IPv6 prefix is Well-Known IPv6 prefix. It is used to reduce overhead to check this; o modify nat64lsn_cfg and nat64stl_cfg structures to use nat64_config structure. And respectivelly modify the rest of code; o remove now unused ro argument from nat64_output() function; o remove __FreeBSD_version ifdef, NAT64 was not merged to older versions; o add commented -DIPFIREWALL_NAT64_DIRECT_OUTPUT flag to module's Makefile as example.
