Vladimir Oltean says: ==================== Fixes for DSA tagging using 802.1Q During the prototyping for the "Decoupling PHYLINK from struct net_device" patchset, the CPU port of the sja1105 driver was moved to a different spot. This uncovered an issue in the tag_8021q DSA code, which used to work by mistake - the CPU port was the last hardware port numerically, and this was masking an ordering issue which is very likely to be seen in other drivers that make use of 802.1Q tags. A question was also raised whether the VID numbers bear any meaning, and the conclusion was that they don't, at least not in an absolute sense. The second patch defines bit fields inside the DSA 802.1Q VID so that tcpdump can decode it unambiguously (although the meaning is now clear even by visual inspection). ==================== 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.
