When in switchdev mode wire traffic will hit the FDB in one of two scenarios. - Shared FDB, in that case traffic from both physical ports should be tagged by the same metadata value so a single FDB rule could catch traffic from both ports. - Two E-Switches, traffic from each physical port will hit the native E-Switch which means traffic from one physical port can't reach the E-Switch of the other one. Looking at those two scenarios it means we can always use the same metadata value to tag wire traffic regardless of the mode. Reserve a single metadata value to be used to tag wire traffic.

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.
