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

The following batch contains Netfilter updates for net-next:

Patch #1 fix checksum calculation in nfnetlink_queue with SCTP,
	 segment GSO packet since skb_zerocopy() does not support
	 GSO_BY_FRAGS, from Antonio Ojea.

Patch #2 extend nfnetlink_queue coverage to handle SCTP packets,
	 from Antonio Ojea.

Patch #3 uses consume_skb() instead of kfree_skb() in nfnetlink,
         from Donald Hunter.

Patch #4 adds a dedicate commit list for sets to speed up
	 intra-transaction lookups, from Florian Westphal.

Patch #5 skips removal of element from abort path for the pipapo
         backend, ditching the shadow copy of this datastructure
	 is sufficient.

Patch #6 moves nf_ct_netns_get() out of nf_conncount_init() to
	 let users of conncoiunt decide when to enable conntrack,
	 this is needed by openvswitch, from Xin Long.

Patch #7 pass context to all nft_parse_register_load() in
	 preparation for the next patch.

Patches #8 and #9 reject loads from uninitialized registers from
	 control plane to remove register initialization from
	 datapath. From Florian Westphal.
