This action requires the VLAN awareness state of the switch to be of the
same type as the key that's being added:
- If the switch is unaware of VLAN, then the tc filter key must only
contain the destination MAC address.
- If the switch is VLAN-aware, the key must also contain the VLAN ID and
PCP.
But this check doesn't work unless we verify the VLAN awareness state on
both the "if" and the "else" branches.

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.
