[PATCH v1 2/3] dts: parameterize ports used in pf_smoke suite

[jspewock@iol.unh.edu]

From: Jeremy Spewock <jspewock@iol.unh.edu>

Currently the pf_smoke testing suite only uses the default ports for
sending and receiving packets. When looking at that suite in isolation,
this is fine since its primary goal is to test the physical functions
in the test run (which the defaults should represent). However, since
this suite represents the same coverage that should be tested on VFs, it
makes sense to parameterize the ports that are in use in the suite so
that the same test cases can be used for testing VFs.
