The MediaTek MT7981 SoC comes with two 1G/2.5G SGMII ports, just like MT7986. In addition MT7981 is equipped with a built-in 1000Base-T PHY which can be used with GMAC1. As many MT7981 boards make use of inverting SGMII signal polarity, add new device-tree attribute 'mediatek,pn_swap' to support them.

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 Restructured Text 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.
