Wrong! _All_ locally defined ip-addresses are internally routed to
lo. Pinging any ip address that a host is setup to receive packets for,
doesnt prove a thing about the functioning of the NIC.
As an experiment, ping any non-lo ip-address on your system. If
ping reports n packets Tx'ed and n packets Rx'ed, your lo interfaces RX
and TX counts will have increased by 2n.
