Or does splitting this cause a bisect > problem? I'm not sure what you're referring to here, and by over-trimming the context, this probably gives an insight into a misunderstanding. This hunk (and the next) does _not_ change what USXGMII ends up with. It moves MAC_2500FD to be under the 10G_QXGMII case from the USXGMII case, and we will _fallthrough_ from the USXGMII case into thte 10G_QXGMII case. So, USXGMII still ends up with MAC_2500FD. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
