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.
Eyal Birger (3):
xfrm: interface: rename xfrm_interface.c to xfrm_interface_core.c
xfrm: interface: Add unstable helpers for setting/getting XFRM
metadata from TC-BPF
selftests/bpf: add xfrm_info tests
