It may avoid some PCS link state bouncing if the writel() came before the printing of the changes in dwmac_ctrl_ane(), as printing those changes will be relatively slow. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
