In the case of vlan filtering on bridges, the bridge may also have the corresponding vlan devices as upper devices. A vlan bridge binding mode is added to allow the link state of the vlan device to track only the state of the subset of bridge ports that are also members of the vlan, rather than that of all bridge ports. This mode is set with a vlan flag rather than a bridge sysfs so that the 8021q module is aware that it should not set the link state for the vlan device. If bridge vlan is configured, the bridge device event handling results in the link state for an upper device being set, if it is a vlan device with the vlan bridge binding mode enabled. This also sets a vlan_bridge_binding flag so that subsequent UP/DOWN/CHANGE events for the ports in that bridge result in a link state update of the vlan device if required. The link state of the vlan device is up if there is at least one bridge port that is a vlan member that is admin & oper up, otherwise its oper state is IF_OPER_LOWERLAYERDOWN.

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.
