dwmac-socfpga uses MII, RMII, GMII, RGMII, SGMII and 1000BASE-X interface modes, and supports the Lynx PCS. The Lynx PCS will only be used for SGMII and 1000BASE-X modes, with the MAC programmed to use GMII or MII mode to talk to the PCS. This suggests that the Synopsys optional dwmac PCS is not present. None of the DTS files set "mac-mode", so mac_interface will be identical to phy_interface. Convert dwmac-socfpga to use phy_interface when determining the interface mode rather than mac_interface.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
