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

following patch set includes netfilter updates for your *net-next* tree.

1. Replace pr_debug use with nf_log infra for debugging in sctp
   conntrack.
2. Remove pr_debug calls, they are either useless or we have better
   options in place.
3. Avoid repeated load of ct->status in some spots.
   Some bit-flags cannot change during the lifeetime of
   a connection, so no need to re-fetch those.
4. Avoid uneeded nesting of rcu_read_lock during tuple lookup.
5. Remove the CLUSTERIP target.  Marked as obsolete for years,
   and we still have WARN splats wrt. races of the out-of-band
   /proc interface installed by this target.
6. Add static key to nf_tables to avoid the retpoline mitigation
   if/else if cascade provided the cpu doesn't need the retpoline thunk.
7. add nf_tables objref calls to the retpoline mitigation workaround.
8. Split parts of nft_ct.c that do not need symbols exported by
   the conntrack modules and place them in nf_tables directly.
   This allows to avoid indirect call for 'ct status' checks.
9. Add 'destroy' commands to nf_tables.  They are identical
   to the existing 'delete' commands, but do not indicate
   an error if the referenced object (set, chain, rule...)
   did not exist, from Fernando.
