Rahul Rameshbabu 8c6210d175 wifi: b43: Disable QoS for bcm4331
[ Upstream commit 09795bded2e725443fe4a4803cae2079cdaf7b26 ]

bcm4331 seems to not function correctly with QoS support. This may be due
to issues with currently available firmware or potentially a device
specific issue.

When queues that are not of the default "best effort" priority are
selected, traffic appears to not transmit out of the hardware while no
errors are returned. This behavior is present among all the other priority
queues: video, voice, and background. While this can be worked around by
setting a kernel parameter, the default behavior is problematic for most
users and may be difficult to debug. This patch offers a working out-of-box
experience for bcm4331 users.

Log of the issue (using ssh low-priority traffic as an example):
    ssh -T -vvvv git@github.com

README

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.
