When ports are standalone (after they left the bridge), they should have no VLAN filtering semantics (they should pass all traffic to the CPU). Currently this is not true for switchdev drivers, because the bridge "forgets" to unset that. Normally one would think that doing this at the bridge layer would be a better idea, i.e. call br_vlan_filter_toggle() from br_del_if(), similar to how nbp_vlan_init() is called from br_add_if(). However what complicates that approach, and makes this one preferable, is the fact that for the bridge core, vlan_filtering is a per-bridge setting, whereas for switchdev/DSA it is per-port. Also there are switches where the setting is per the entire device, and unsetting vlan_filtering one by one, for each leaving port, would not be possible from the bridge core without a certain level of awareness. So do this in DSA and let drivers be unaware of it.

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.
