Well, technically Intel LXT971A is a 10/100 PHY. It does not support GigE
but strangely it refers to 1000 mode in status and register 0x9 and 0xA
but then again puts a note and says not implemented. It looks like either
half implemented GigE design sold as 10/100 PHY.

For this particular case LXT971A is returning 0x1fff for register 0xA.

I am afraid I cannot say that. Perhaps folks on the list try "mii read"
command to test if register 0xA is returning other than 0xffff.
