It's useful for drivers supporting bridge offload to be able to query the bridge's VLAN filtering state. Currently, upon enslavement to a bridge master, the offloading driver will only learn about the bridge's VLAN filtering state after the bridge device was already linked with its slave. Being able to query the bridge's VLAN filtering state allows such drivers to forbid enslavement in case resource couldn't be allocated for a VLAN-aware bridge and also choose the correct initialization routine for the enslaved port, which is dependent on the bridge type.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
