sure,
i use it ingress,
so, i need to use tc xt action
to get mark on the packet, before filter on ifb will run.

prerouting rule, in turn, used to test if mark was actually restored.

in practice:
1. prerouting rule - is not fired. so, no packets with mark was seen.
2. filter on ifb - do not pass traffic to flow configured.
looks like `CONNMARK --restore` is not really called.
