W/o doing any research myself, I vaguely remember someone here having
similar results and suggesting that some nics have a design such that
some ports are tied together as a result of sharing components on the
nic itself. Basically, you may have a nic that is really only two
independent nics, each with two ports so you have to pass two in at
once etc.

A quick search or test should validate this...
