If a VF has been configured and the user later clears all QoS settings, the vport element remains in the firmware QoS tree. This leads to inconsistent behavior compared to VFs that were never configured, since the FW assumes that unconfigured VFs are outside the QoS hierarchy. As a result, the bandwidth share across VFs may differ, even though none of them appear to have any configuration. Align the driver behavior with the FW expectation by destroying the vport QoS element when all configurations are removed.

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.
