Subject: [PATCH net 0/7] Netfilter fixes for net

Hi,

The following patchset contains Netfilter fixes for net:

1) Fix NAT support for NFPROTO_INET without layer 3 address,
   from Florian Westphal.

2) Use kfree_rcu(ptr, rcu) variant in nf_tables clean_net path.

3) Use list to collect flowtable hooks to be deleted.

4) Initialize list of hook field in flowtable transaction.

5) Release hooks on error for flowtable updates.

6) Memleak in hardware offload rule commit and abort paths.

7) Early bail out in case device does not support for hardware offload.
   This adds a new interface to net/core/flow_offload.c to check if the
   flow indirect block list is empty.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git

Thanks.
