This warning can trigger if there is a mismatch between frames that were sent with the sta pointer set vs tx status frames reported for the sta address. This can happen due to race conditions on re-creating stations, or even in the case of .sta_add/remove being used instead of .sta_state, which can cause frames to be sent to a station that has not been uploaded yet. If there is an actual underflow issue, it should show up in the device airtime warning below, so it is better to remove this one.

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.
