The purpose of this change is to use such linked-list in sorting or
ordering some kind of items (e.g. flowtop - flows, columns).

t it can be implemented for 1 process-only in the while(...)
loop when reading mmap-ed frames from kernel by checking
sniffed number of packets ? For the fan-out group processes it seems
like it needs to check each N packet on the kernel side (eBPF might
help ?) ?
It would be good to hear comments fr
/"$(date

Add trafgen_l4.c module with implementation
of UDP header fields gneration.
UDP proto generation logic automaticaly sets by default
IPPROTO_UDP to the lower proto if it is IPv4, also cscum is
