Hi Andrew,
Such mechanisms are standardized and supported by pretty much all devices in the market. The Open Alliance specification is publicly available here: http://www.opensig.org/download/document/218/Advanced_PHY_features_for_automotive_Ethernet_V1.0.pdf
As the specification is newer than the 100BASE-T1 spec, do not expect first generation devices to follow the register definitions as per Open Alliance. But for future devices, also registers should be same across different vendors.
