BMSR register value is 111100011001101 even when using FX mode, which doesn't allow auto negotiation. Note however that bit 3, AUTO-NEGOTIATION ABILITY appears a 1, so typical drivers aren't able to use this information to disable autonegotiation.
I'm thinking of using alternatively bit 12 of BMCR, AUTO-NEGOTIATION ENABLE to check strap initial value al rest, but this doesn't seem like the proper way to do it. Any suggestions?
Thanks!
