Note that the +rrqnet+ virtual cable requires real networking for its
UDP tunnel traffic. The real packets will have a UDP header in
addition to the orignal packet, which means that it grows packets with
24 or 48 bytes (for ipv4 and ipv6 respectively). This may cause packet
fragmentation of the tunneling packets unless the associated +tap+ is
configured with that much smaller MTU than the real traffic.
