[iptables-nftables RFC PATCH 0/6] IPv6 Support

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

Hi,

Here is an attempt to get iptables-nftables supporting IPv6.
I haven't tested it really, so I send it more as an RFC.

Starting from xtables.c which supports only IPv4, patch 2 combines the support for IPv6 in it.
The family attribute provided in patch 1 is set then used in nft.c to use it accordingly, in patch 3.

Patch 4 finalizes it in handling the right informations for rule manipulations depending on the family.

Patch 5 and 6 then adds the support of IPv6 when it comes to respectively save and print the firewall.

Please review,

Tomasz Bursztyka (6):
  nft: Add a family attribute to nft_handle
  xtables: Combine IPv6 support with IPv4 support
  nft: Use handle's family attribute instead of hardcoded AF_INET one
  nft: Support IPv6 rules manipulation
  nft: Use the right payload parsing function when saving a rule
  nft: Handle IPv6 when printing out firewall rules
