The functional changes look good, but I would like to see some
description of what the XL part stands for here.

While you are modifying this, do you also mind submitting a Device Tree
specification change:

https://www.devicetree.org/specifications/

Thanks!

Thank you for the information.

Currenlty, the XLGMAC is a new IP from Synopsys. We are using a PCI driver for
testing on FPGA platform.  Is it possible to add these changes first and submit
a device tree in the future?

I think Florian wants to know about the IEEE standard or what ever
which defines what the phy-mode XLGMAC is, in the same way there are
standards for RGMII, SGMII, etc.
