The supported-interfaces bits are raw phy_interface_t values. OpenWrt's
layerscape kernel inserts PHY_INTERFACE_MODE_2500SGMII between
2500BASEX and 5GBASER, so on that kernel every bit above 2500BASEX
means something different than on mainline.

There's no such thing as 2500SGMII :/

This is an openwrt problem, they need to make sure their kernel headers
matches the kernel they are running...
