Please explain why and how a PHY may not appear to be present using C22 frames to read the ID registers, but does appear to be present when using C22 frames to the C45 indirect registers - and summarise which PHYs have this behaviour. It seems very odd that any PHY would only implement C45 indirect registers in the C22 register space. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
