commitc263f644adupstream. For the device SP, the firmware version is a 32-bit value where the lower 20 bits represent the base version number. And the customized firmware version populates the upper 12 bits with a specific identification number. For other devices AML 25G and 40G, the upper 12 bits of the firmware version is always non-zero, and they have other naming conventions. Only SP devices need to check this to tell if XPCS will work properly. So the judgement of MAC type is added here. And the original logic compared the entire 32-bit value against 0x20010, which caused the outdated base firmwares bypass the version check without a warning. Apply a mask 0xfffff to isolate the lower 20 bits for an accurate base version comparison.

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.
