[PATCH net-next 00/16] Netfilter updates for net-next

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi,

The following patchset contains Netfilter updates for net-next:

1) Support for SCTP chunks matching on nf_tables, from Phil Sutter.

2) Skip LDMXCSR, we don't need a valid MXCSR state. From Stefano Brivio.

3) CONFIG_RETPOLINE for nf_tables set lookups, from Florian Westphal.

4) A few Kconfig leading spaces removal, from Juerg Haefliger.

5) Remove spinlock from xt_limit, from Jason Baron.

6) Remove useless initialization in xt_CT, oneliner from Yang Li.

7) Tree-wide replacement of netlink_unicast() by nfnetlink_unicast().

8) Reduce footprint of several structures: xt_action_param,
   nft_pktinfo and nf_hook_state, from Florian.

10) Add nft_thoff() and nft_sk() helpers and use them, also from Florian.

11) Fix documentation in nf_tables pipapo avx2, from Florian Westphal.

12) Fix clang-12 fmt string warnings, also from Florian.

Thank you!
