Subject: [PATCH] q_cake: Add support for setting the fwmark option
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
