Yes for sure - the best for my use case will be to implement XDP :)

But for real life not test lab use programs like xdp_fwd need to be 
extended for minimal information needed from IP router - like counters 
and some aditional debug for traffic like sniffing / sampling for ddos 
detection.

And that is rly minimum needed - for routing IP traffic with XDP
