+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds support for the newly added fwmark option to CAKE, which allows
+overriding the tin selection from the per-packet firewall marks. The fwmark
+field is a bitmask that is applied to the fwmark to select the tin.

++ This options turns on fwmark-based overriding of CAKE's tin selection.
++If set, the option specifies a bitmask that will be applied to the fwmark
++associated with each packet. If the result of this masking is non-zero, the
++result will be right-shifted by the number of least-significant unset bits in
++the mask value, and the result will be used as a the tin number for that packet.
++This can be used to set policies in a firewall script that will override CAKE's
++built-in tin selection.
