Subject: [PATCH net-next v2 3/7] net: fsl/fman: add support for PHY_INTERFACE_MODE_XFI

Add support in the code for the XFI PHY interface mode. Although
the interfaces did not use XGMII, the device trees described the
interface type as XGMII and the code was written with XGMI as an
indicator for 10G. The patch does not remove XGMII as a transition
time will be required until the device trees, fix-ups performed
by bootloaders are all aligned.
