The 'qec' dma engine appears to be much like the 'hme' engine, so it may be
able to do full duplex.  The problem is the phy on the 'qec+be' doesn't
claim to do full duplex, and no amount of coaxing can convince it to do it
(nsphy when found on the hme requires a bit of convincing about full duplex
operation).  My guess is that if an external phy capable of full duplex is
hooked up to a 'qec+be', then the card might be able to do full duplex, but
the onboard phy won't do it.
