QUIC/inet/tests/module/UDP_ttl_ipv4.test

%description:
Tests that TimeToLive UDP socket option takes effect over IPv4.

NClients example network is used, with one client.
The client sends a packet with a given TTL.
It is checked that the server receives the datagram with the
given TTL minus the number of hops.
