There has been a few errors in the ethtool reply size calculations, most of those are hard to trigger during basic testing because of skb size rounding up and netdev names being shorter than max. Add a more precise check. This change will affect the value of payload length displayed in case of -EMSGSIZE but that should be okay, "payload length" isn't a well defined term here.

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.
