-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.
