FYI, applied http://patchwork.ozlabs.org/project/netdev/list/?series=8462&state=* on 4.14.x and I still see: libphy: Fixed MDIO Bus: probed tun: Universal TUN/TAP device driver, 1.6 libphy: Freescale XGMAC MDIO Bus: probed iommu: Adding device ffe488000.port to group 10 libphy: Freescale XGMAC MDIO Bus: probed mdio_bus ffe4e1000: Error while reading PHY0 reg at 3.3 iommu: Adding device ffe489000.port to group 22 libphy: Freescale XGMAC MDIO Bus: probed mdio_bus ffe4e3000: Error while reading PHY0 reg at 3.3 iommu: Adding device ffe48a000.port to group 23 libphy: Freescale XGMAC MDIO Bus: probed mdio_bus ffe4e5000: Error while reading PHY0 reg at 3.3 iommu: Adding device ffe48b000.port to group 24 libphy: Freescale XGMAC MDIO Bus: probed mdio_bus ffe4e7000: Error while reading PHY0 reg at 3.3 iommu: Adding device ffe48c000.port to group 25 libphy: Freescale XGMAC MDIO Bus: probed mdio_bus ffe4e9000: Error while reading PHY0 reg at 3.3 Other than that, FMAN appears to be working.
