Most DSA switch tags shift the EtherType to the right, causing the master to not parse the VLAN as VLAN. However, not all switches do that (example: tail tags, tag_8021q etc), and if the DSA master has "rx-vlan-filter: on" in ethtool -k, then we have a problem. Therefore, we could populate the VLAN table of the master, just in case (for some switches it will not make a difference), so that network I/O can work even with a VLAN filtering master.

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.
