ENETC has a register PSPEED to indicate the link speed of hardware. It is need to update accordingly. PSPEED field needs to be updated with the port speed for QBV scheduling purposes. Or else there is chance for gate slot not free by frame taking the MAC if PSPEED and phy speed not match. So update PSPEED when link adjust. This is implement by the adjust_link.

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.
