NAME

       skbedit - SKB editing action

SYNOPSIS

       tc ... action skbedit [ queue_mapping QUEUE_MAPPING ] [ priority PRIORITY ] [ mark MARK ] ptype PTYPE ]

DESCRIPTION

       The  skbedit action allows to change a packet's associated meta data. It complements the pedit action, which in turn allows to change parts
       of the packet data itself.

       The most unique feature of skbedit is it's ability to decide over which queue of an interface with multiple transmit queues the	packet	is
       to  be  sent  out. The number of available transmit queues is reflected by sysfs entries within /sys/class/net/<interface>/queues with name
       tx-N (where N is the actual queue number).

OPTIONS

       queue_mapping QUEUE_MAPPING
	      Override the packet's transmit queue. Useful when applied to packets transmitted over MQ-capable network interfaces.   QUEUE_MAPPING
	      is an unsigned 16bit value in decimal format.

       priority PRIORITY
	      Override the packet classification decision.  PRIORITY is either root, none or a hexadecimal major class ID optionally followed by a
	      colon (:) and a hexadecimal minor class ID.

       mark MARK
	      Change the packet's firewall mark value.	MARK is an unsigned 32bit value in automatically detected format (i.e., prefix	with  '0x'
	      for hexadecimal interpretation, etc.).

       ptype PTYPE
	      Override	the  packet's  type.  Useful  for  setting packet type to host when needing to allow ingressing packets with the wrong MAC
	      address but correct IP address.  PTYPE is one of: host, otherhost, broadcast, multicast

NAME

       fw - fwmark traffic control filter

SYNOPSIS

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

DESCRIPTION

       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 fil-
       ter matches.  iptables allows to mark single 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 classifi-
       cation 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.

OPTIONS

       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.

EXAMPLES

       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
