[ Upstream commit d83b8aa5207d81f9f6daec9888390f079cc5db3f ]
The bit-masks used for the TXERRCH and RXERRCH (tx and rx error channels)
are incorrect and always lead to a zero result. The mask values are
currently the incorrect post-right shifted values, fix this by setting
them to the currect values.
(I double checked these against the TMS320TCI6482 data sheet, section
5.30, page 127 to ensure I had the correct mask values for the TXERRCH
and RXERRCH fields in the MACSTATUS register).
Addresses-Coverity: ("Operands don't affect result")

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.
