Someone else has already pointed-out the lspci stuff so instead I'll
say:

At one point that assertion was probably true, however I suspect that
if that assertion has not already aged beyond accuracy for some
definition of "current hardware," it will shortly. Virtually every
dual-port GbE interface with which I am familiar has a bus interface
capable of driving both ports simultaneously at or near to capacity.

Then, perhaps I live in a different context from Frank Stutzman.
