Below EST errors are added into ethtool statistic: 1) Constant Gate Control Error (CGCE): The counter "mtl_est_cgce" increases everytime CGCE interrupt is triggered. 2) Head-of-Line Blocking due to Scheduling (HLBS): The counter "mtl_est_hlbs" increases everytime HLBS interrupt is triggered. 3) Head-of-Line Blocking due to Frame Size (HLBF): The counter "mtl_est_hlbf" increases everytime HLBF interrupt is triggered. 4) Base Time Register error (BTRE): The counter "mtl_est_btre" increases everytime BTRE interrupt is triggered but BTRL not reaches maximum value of 15. 5) Base Time Register Error Loop Count (BTRL) reaches maximum value: The counter "mtl_est_btrlm" increases everytime BTRE interrupt is triggered and BTRL value reaches maximum value of 15. Please refer to MTL_EST_STATUS register in DesignWare Cores Ethernet Quality-of-Service Databook for more detail explanation.

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.
