The priority packet and byte counters in ethtool -S are returned by the driver based on the pri2cos mapping. The assumption is that each priority is mapped to one and only one hardware CoS queue. In a special RoCE configuration, the FW uses combined CoS queue 0 and CoS queue 1 for the priority mapped to CoS queue 0. In this special case, we need to add the CoS queue 0 and CoS queue 1 counters for the priority packet and byte counters.

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 reStructuredText 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.
