commit b712941c8085e638bb92456e866ed3de4404e3d5 upstream.
In the absence of this validation, if the user requests to
configure queues more than the enabled queues, it results in
sending the requested number of queues to the kernel stack
(due to the asynchronous nature of VF response), in which
case the stack might pick a queue to transmit that is not
enabled and result in Tx hang. Fix this bug by
limiting the total number of queues allocated for VF to
active queues of VF.

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.
