Currently all flows for a certain SA must be processed by the same cpu to avoid packet reordering and lock contention of the xfrm state lock. To get rid of this limitation, the IETF standardized per cpu SAs in RFC 9611. This patch implements the xfrm part of it. We add the cpu as a lookup key for xfrm states and a config option to generate acquire messages for each cpu. With that, we can have on each cpu a SA with identical traffic selector so that flows can be processed in parallel on all cpus.
