In the case of vlan filtering on bridges, the bridge may also have the corresponding vlan devices as upper devices. Currently the link state of vlan devices is transferred from the lower device. So this is up if the bridge is in admin up state and there is at least one bridge port that is up, regardless of the vlan that the port is a member of. The link state of the vlan device may need to track only the state of the subset of ports that are also members of the corresponding vlan, rather than that of all ports. Add a flag to specify a vlan bridge binding mode, by which the link state is no longer automatically transferred from the lower device, but is instead determined by the bridge ports that are members of the vlan.

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.
