Ido Schimmel 6c94a12c92 selftests: mirror_gre_bridge_1q: Avoid changing PVID while interface is operational 
commit 3122257c02 upstream.

In emulated environments, the bridge ports enslaved to br1 get a carrier
before changing br1's PVID. This means that by the time the PVID is
changed, br1 is already operational and configured with an IPv6
link-local address.

When the test is run with netdevs registered by mlxsw, changing the PVID
is vetoed, as changing the VID associated with an existing L3 interface
is forbidden. This restriction is similar to the 8021q driver's
restriction of changing the VID of an existing interface.

Fix this by taking br1 down and bringing it back up when it is fully
configured.

With this fix, the test reliably passes on top of both the SW and HW
data paths (emulated or not).

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.
