As there are several variants of the PHY, the last letter might be significant.
Eg. Some of the PHYs only support a single interface, some support two (which is a huge difference if an extra control-register needs to be initialized).
If this dual interface could work some day, then I think it would be awesome, because the price from IOCrest’s store is only around $18.
In best case, that’d give us 4.5 Gbit raw transfer rate, which would make the EspressoBIN quite interesting for build farm controllers and NAS (but also as a router).
