Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next, they are:

1) Release nf_tables objects on netns destructions via
   nft_release_afinfo().

2) Destroy basechain and rules on netdevice removal in the new netdev
   family.

3) Get rid of defensive check against removal of inactive objects in
   nf_tables.

4) Pass down netns pointer to our existing nfnetlink callbacks, as well
   as commit() and abort() nfnetlink callbacks.

5) Allow to invert limit expression in nf_tables, so we can throttle
   overlimit traffic.

6) Add packet duplication for the netdev family.

7) Add forward expression for the netdev family.

8) Define pr_fmt() in conntrack helpers.

9) Don't leave nfqueue configuration on inconsistent state in case of
   errors, from Ken-ichirou MATSUZAWA, follow up patches are also from
   him.

10) Skip queue option handling after unbind.

11) Return error on unknown both in nfqueue and nflog command.

12) Autoload ctnetlink when NFQA_CFG_F_CONNTRACK is set.

13) Add new NFTA_SET_USERDATA attribute to store user data in sets,
    from Carlos Falgueras.

14) Add support for 64 bit byteordering changes nf_tables, from Florian
    Westphal.

15) Add conntrack byte/packet counter matching support to nf_tables,
    also from Florian.
