Petr Machata says: ==================== bridge: Handle changes in VLAN_FLAG_BRIDGE_BINDING When bridge binding is enabled on a VLAN netdevice, its link state should track bridge ports that are members of the corresponding VLAN. This works for a newly-added netdevices. However toggling the option does not have the effect of enabling or disabling the behavior as appropriate. In this patchset, have bridge react to bridge_binding toggles on VLAN uppers. There has been another attempt at supporting this behavior in 2022 by Sevinj Aghayeva [0]. A discussion ensued that informed how this new patchset is constructed, namely that the logic is in the bridge as opposed to the 8021q driver, and the bridge reacts to NETDEV_CHANGE events on the 8021q upper. Patches #1 and #2 contain the implementation, patches #3 and #4 a selftest.

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 reStructuredText 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.
