Right, so in the MAC-to-MAC setup that is being discussed in this thread, the _local_ side MAC where phy-mode is specified should not care which of the RGMII modes is specified, because the delays are a function of "the other side" of the link. So, the proposal that macb should limit itself to only accepting "rgmii" in it's _local_ phy-mode property because the _local_ MAC does not support delays is wrong. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
