Extending functionality of recently sent nftables flow offload.
This Series contains 2 Patches where the second is for RFC, because i cannot test it,
but it is reported by author as working and i should send it
Series depend on HW offload Patches:
https://patchwork.ozlabs.org/project/netfilter-devel/list/?series=233310&archive=both&state=*
Frank Wunderlich (2):
