     NAME
          matchall - traffic control filter that matches every packet

     SYNOPSIS
          tc filter ... matchall [ skip_sw | skip_hw  ] [ action
                  ACTION_SPEC ] [  classid CLASSID ]

     DESCRIPTION
          The matchall filter allows to classify every packet that
          flows on the port and run a action on it.

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

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

          skip_sw
               Do not process filter by software. If hardware has no
               offload support for this filter, or TC offload is not
               enabled for the interface, operation will fail.

          skip_hw
               Do not process filter by hardware.

     EXAMPLES
          To create ingress mirroring from port eth1 to port eth2:

               tc qdisc  add dev eth1 handle ffff: ingress
               tc filter add dev eth1 parent ffff:           \
                       matchall skip_sw                      \
                       action mirred egress mirror           \
                       dev eth2

          The first command creates an ingress qdisc with handle ffff:
          on device eth1 where the second command attaches a matchall
          filters on it that mirrors the packets to device eth2.

          To create egress mirroring from port eth1 to port eth2:

               tc qdisc add dev eth1 handle 1: root prio
               tc filter add dev eth1 parent 1:               \
                       matchall skip_sw                       \
                       action mirred egress mirror            \
                       dev eth2

          The first command creates an egress qdisc with handle 1:
          that replaces the root qdisc on device eth1 where the second
          command attaches a matchall filters on it that mirrors the
          packets to device eth2.

          To sample one of every 100 packets flowing into interface
          eth0 to psample group 12:

               tc qdisc add dev eth0 handle ffff: ingress
               tc filter add dev eth0 parent ffff: matchall \
                    action sample rate 100 group 12
