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