The linux-next integration testing tree

DSA assumes that a bridge which has vlan filtering disabled is not vlan aware, and ignores all vlan configuration. However, the kernel software bridge code allows configuration in this state. This causes the kernel's idea of the bridge vlan state and the hardware state to disagree, so "bridge vlan show" indicates a correct configuration but the hardware lacks all configuration. Even worse, enabling vlan filtering on a DSA bridge immediately blocks all traffic which, given the output of "bridge vlan show", is very confusing. Provide an option that drivers can set to indicate they want to receive vlan configuration even when vlan filtering is disabled. At the very least, this is safe for Marvell DSA bridges, which do not look up ingress traffic in the VTU if the port is in 8021Q disabled state. It is also safe for the Ocelot switch family. Whether this change is suitable for all DSA bridges is not known.

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.
