Add some user interface for usage, for example at RK3399:
- scan rgmii delayline:
echo (speed:10 100 1000) > /sys/devices/platform/fe300000.ethernet/phy_lb_scan
- loopback test:
echo (speed:10 100 1000) > /sys/devices/platform/fe300000.ethernet/phy_lb
echo (speed:10 100 1000) > /sys/devices/platform/fe300000.ethernet/mac_lb
- set/show delayline
cat /sys/devices/platform/fe300000.ethernet/rgmii_delayline
echo (tx delayline) (rx delayline) > /sys/devices/platform/fe300000.ethernet/rgmii_delayline

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
