The MSCC MIIM MDIO driver uses delays to read poll a status register. I made multiple tests on a Ocelot PCS120 platform which led me to reduce those delays. The delay in between which the polling function is allowed to sleep is reduced from 100us to 50us which in almost all cases is a good value to succeed at the first retry. The overall delay is also lowered as the prior value was really way to high, 10000us is large enough.

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.
