The felix driver, which also has a tagging protocol implementation based on tag_8021q, does not care about adding the RX VLAN that is pvid on one port on the other ports that are in the same bridge with it. It simply doesn't need that, because in its implementation, the RX VLAN that is pvid of a port is only used to install a TCAM rule that pushes that VLAN ID towards the CPU port. Now that tag_8021q no longer performs Shared VLAN Learning based forwarding, the RX VLANs are actually segregated into two types: standalone VLANs and VLAN-unaware bridging VLANs. Since you actually have to call dsa_tag_8021q_bridge_join() to get a bridging VLAN from tag_8021q, and felix does not do that because it doesn't need it, it means that it only gets standalone port VLANs from tag_8021q. Which is perfect because this means it can drop its workarounds that avoid the VLANs it does not need. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

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.
