Subject: [PATCH v3 ipsec-next 0/4] Add support for RFC 9611 per cpu xfrm states.

This patchset implements the xfrm part of per cpu SAs as specified in
RFC 9611.

Patch 1 adds the cpu as a lookup key and config option to to generate
acquire messages for each cpu.

Patch 2 caches outbound states at the policy.

Patch 3 caches inbound states on a new percpu state cache.

Patch 4 restricts percpu SA attributes to specific netlink message types.

Please review and test.

Changes from v2:

- Rebase to ipsec-next

- Describe new xfrm_policy struct member state_cache_list

- Drop a missplaced semicolon

Changes from v1:

- Add compat layer attributes

- Fix a 'use always slowpath' condition

- Document get_cpu() usage

- Fix forgotten update of xfrm_expire_msgsize()

Thanks!
