Yeah, that's the whole problem. If I look at the datasheets I can find about the F model, it would seem the chip identification will not match at all. In practice, it turns out people with a chip labeled as FC have a register set very similar to what is in the M datasheet, *including* Chip Identification on A0h/A1h with value 0007:1023h! Read the thread for more details and a good deal of confusion. The Chip ID is read in the _fixup routine, because it is a non-standard method of identification. Normally, PHYs are identified differently. By the way, I didn't write the chip detection. Ironically, it was written to match the F model :).
