mlx5e_build_rq_frags_info() assumes that MTU is not bigger than PAGE_SIZE * MLX5E_MAX_RX_FRAGS, which is 16K for 4K pages. Currently, the firmware limits MTU to 10K, so the assumption doesn't lead to a bug. This commits adds an additional driver check for reliability, since the firmware boundary might be changed. The calculation is taken to a separate function with a comment explaining it. It's a preparation for the following patches that introcuce XDP multi buffer support.

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.
