[ Upstream commit a7bf4d5063c7837096aab2853224eb23628514d9 ]
The previous calculation used roundup() which caused an overflow for
rates between 25.5Gbps and 26Gbps.
For example, a rate of 25.6Gbps would result in using 100Mbps units with
value of 256, which would overflow the 8 bits field.
Simplify the upper_limit_mbps calculation by removing the
unnecessary roundup, and adjust the comparison to use <= to correctly
handle the boundary condition.

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.
