commitb8056e8434upstream. We have logic to maintain network counters across resets by storing the counters in bp->net_stats_prev before reset. But not all resets will clear the counters. Certain resets that don't need to change the number of rings do not clear the counters. The current logic accumulates the counters before all resets, causing big jumps in the counters after some resets, such as ethtool -G. Fix it by only accumulating the counters during reset if the irq_re_init parameter is set. The parameter signifies that all rings and interrupts will be reset and that means that the counters will also be reset.

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.
