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 one 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: clsact
	      tc filter add dev eth1 ingress		    \
		      matchall skip_sw			    \
		      action mirred egress mirror	    \
		      dev eth2

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

       To create egress mirroring from port eth1 to port eth2:

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

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

       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
