       fw - fwmark traffic control filter

       tc filter ... fw [ classid CLASSID ] [ action ACTION_SPEC ]

       the fw filter allows to classify packets based on a previously set fwmark by iptables.  If
       it is identical to the filter's handle, the filter matches.  iptables allows to mark  sin-
       gle  packets  with  the  MARK target, or whole connections using CONNMARK.  The benefit of
       using this filter instead of doing the heavy-lifting with tc itself is that on one hand it
       might  be  convenient  to  keep packet filtering and classification in one place, possibly
       having to match a packet just once, and on the other users familiar with iptables but  not
       tc will have a less hard time adding QoS to their setups.

       classid CLASSID
              Push matching packets to the class identified by CLASSID.

       action ACTION_SPEC
              Apply an action from the generic actions framework on matching packets.

       Take e.g. the following tc filter statement:

              tc filter add ... handle 6 fw classid 1:1

       will match if the packet's fwmark value is 6.  This is a sample iptables statement marking
       packets coming in on eth0:

              iptables -t mangle -A PREROUTING -i eth0 -j MARK --set-mark 6
