Definitely no or at least not in any visible way:
- no drop in netstat -s for either UDP nort IPv4
- if I snoop at the same time on the receiving interface, I get the
right number of packets.

I'd love to do that anyway but in fact this is only doable by a setsockopt
syscall (SO_RCVBUF) and there's not option in the config file to do it.
I'll try to do it but I'm not sure the cause is here.
