<para>The existence of both TC_BITS and MASK_BITS is owed to the way that
WIDE_TC_MARKS was originally implemented. Note that TC_BITS is 14 rather
than 16 when WIDE_TC_MARKS=Yes.</para>
<para>Beginning with Shorewall 4.4.12, the field between MASK_BITS and
PROVIDER_OFFSET can be used for any purpose you want. </para>
