<para>Defines a mapping of Linux internal packet priority (<constant>SO_PRIORITY</constant>) to VLAN header
PCP field for incoming frames. Takes a whitespace-separated list of unsigned integer pairs in the format
<literal>from</literal>-<literal>to</literal>, e.g., <literal>21-7 45-5</literal> ranges 1–4294967294.
Note that <literal>from</literal> must be greater than or equal to <literal>to</literal>. When unset,
the kernel's default will be used.
