Merge branch 'xfrm: interface: Add unstable helpers for XFRM metadata'
Eyal Birger says:
====================
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.
---
changes in v6: fix sparse warning in patch 2
changes in v5:
- avoid cleanup of percpu dsts as detailed in patch 2
changes in v3:
- tag bpf-next tree instead of ipsec-next
- add IFLA_XFRM_COLLECT_METADATA sync patch
====================
