I was looking to emulate something closer to a tcp or udp
echo server, so testpmd sounded like the better example
to follow. However, I'm not sure how the echo server
example is supposed to be configured - does it take *any*
incoming echo request on the interface and reflect it back,
or is this restricted to some subset  of "for-us" packets (i.e., sent to
"locally configured address")?

Also, does the sender need a statically configured arp entry
so that the echo request gets delivered?
