I had a quick look at the source of ipt_layer7, it's linearising 
the skb so that the pattern can be matched. For ipp2p, it simply 
skip the non-linear skb (and it has been accepted into pom-ng).

So I think it should be quite easy if one wants to also handle 
the non-linear case, ie just linearise the skb. Not efficient, but
it should work. Right ?

Cheers.
