[RFC] testpmd: use RFC2544 reserved IP addresses

[Stephen Hemminger <stephen@networkplumber.org>]

Change the transmit only side of testpmd to use the IP addresses
that are marked as reserved for benchmarking by RFC2544 192.18.0.0/27;
rather than the commonly used subnet 192.168.0.0/24 which is likely
to used for administrative interface.
