I started to think that I will change logic of adding same proto
headers, because in this version same proto header
might be added only once, but I think lets user decide the order or
headers, so it will allow to easy construct icmp
unreach packets like:
{ eth(...), ip(da=3.3.3.3), icmp(unreach), ip(...) }
or build tuneling headers.
But sure there will be still automatically adding of lower layer proto
when user specify only higher protos.
So I will rework it in v2 but you can still look on the main concept
of the whole feature.
