[PATCH ipsec-next 0/3] xfrm: interface: Add unstable helpers for XFRM metadata

by Eyal Birger

This patch series adds xfrm metadata helpers using the unstable kfunc call interface for the TC-BPF hooks. This allows steering traffic towards different IPsec connections based on logic implemented in bpf programs. The helpers are integrated into the xfrm_interface module. For this purpose the main functionality of this module is moved to xfrm_interface_core.c.
