[nf-next:nf_tables-experiments PATCH 0/4] NAT expression and IPv6 NAT support

[Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>]

Hi,

Here 4 patches to set up NAT expression and related IPvx chains.
It's an adaptation of existing code (splitting nft_chain_ipv4_nat.c and taking code from ip6tables_nat.c),
that's why I kept former Copyrights even in the new modules created.

In nft_nat.c, I used memcpy() on ipv6 data, let me know if there is a better way (though I guess gcc optimizes it).

Please review,

Tomasz Bursztyka (4):
  nf_tables: Change NFTA_NAT_ attributes to better semantic
    significance
  nf_tables: Split IPv4 NAT into NAT expression and NAT IPv4 chain
  nf_tables: Add support for IPv6 NAT expression
  nf_tables: Add support for IPv6 NAT chain
