How about moving all driver specific tests to driver/net/<driver>/?
I think, it wont scale if everyone starts adding their own
driver specific tests to testpmd.

How about creating 
#A generic string parser in testpmd?  something like,
port config (port_id) <driver name> ....
# and do driver_name to port_id lookup
# and introduce "test" or "self_test" ops in ethdev
# and call "test" op on the selected port_id
