Vendor specific PHY registers should be in MMS 4 which is MMD 31, where the PHY driver can access them. Table 6 says: "PHY – Vendor Specific" for MMS 4, so clearly that is where the standards committee expected PHY vendor registers to be. Anyway, does the PHY driver actually need to access MMS 12? Or can the MAC driver do it? That is the same question i asked Ramón about the Microchip part. We really should avoid layering violations as much as we can, and we should not have the framework make it easy to violate layering. We want all such horrible hacks hidden in the MAC driver which needs such horrible hacks because of bad design. Andrew
