Ido Schimmel dcaf06afaa selftests: net: Fix bridge backup port test flakiness 
[ Upstream commit 38ee0cb2a2 ]

The test toggles the carrier of a bridge port in order to test the
bridge backup port feature.

Due to the linkwatch delayed work the carrier change is not always
reflected fast enough to the bridge driver and packets are not forwarded
as the test expects, resulting in failures [1].

Fix by busy waiting on the bridge port state until it changes to the
desired state following the carrier change.

 # TEST: swp1 carrier off                                              [ OK ]
 # TEST: No forwarding out of swp1                                     [FAIL]
 [  641.995910] br0: port 1(swp1) entered disabled state
 # TEST: No forwarding out of vx0                                      [ OK ]

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.
