====================
pull request (net-next): ipsec-next 2024-05-03

1) Remove Obsolete UDP_ENCAP_ESPINUDP_NON_IKE Support.
   This was defined by an early version of an IETF draft
   that did not make it to a standard.

2) Introduce direction attribute for xfrm states.
   xfrm states have a direction, a stsate can be used
   either for input or output packet processing.
   Add a direction to xfrm states to make it clear
   for what a xfrm state is used.
