DP83867ERGZ-R-EVM: Enable Auto-negotiation and detect 10/100/1000 Base -T capability using MDIO with no MAC interface

Tool/software:

Hi,

My application needs detect Link partner capability that is whether the Link partner is 10/100/1000 Base-T capable, half/full duplex etc. I dont need to do any communication with the link partner and the requirement is limited to knowing the link partner capability.

I want to know if DP83867 is able to perform this without any MAC or GMII (or other interface) and using only USB-MDIO interface. That is if I access the registers using MDIO, enable auto negotiation and read back the registers after auto negotiation is completed. I know this is possible for 10/100Base -T, the question is if it would work for 1000 Base-T as well.

Has anybody checked this and kindly share your valuable feedback.

Thanks,

Jithin
