Currently, the window_drop stats persist even if an incorrect Qdisc was
removed from the interface and a new one is installed. This is because
the enetc driver keeps the state, and that is persistent across multiple
Qdiscs.
To resolve the issue, clear all win_drop counters from all TX queues
when the currently active Qdisc is removed. These counters are zero
by default. The counters visible in ethtool -S are also affected,
but I don't care very much about preserving those enough to keep them
monotonically incrementing.

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.
