FYI, I've now reworked my dump patch series to use your netfilter infrastructure - worked out fine and it was pretty easy since your netfilter infrastructure is very usable! I'll polish my patches a little bit more, then I'll send them out, too. So I am looking forward to see your netfilter infrastructure included in upstream soon :-) Thomas
