NAME
       skbedit - SKB editing action

SYNOPSIS
       tc ... action skbedit [ queue_mapping QUEUE_MAPPING ] [ priority
	       PRIORITY ] [ mark MARK[/MASK] ] [ ptype PTYPE ] [
	       inheritdsfield ]

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

       The most unique feature of skbedit is its 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[/MASK]
	      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.).  MASK defines the
	      32-bit mask selecting bits of mark value. Default is 0xffffffff.

       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

       inheritdsfield
	      Override the packet classification decision, and any value
	      specified with priority,	using the information stored in the
	      Differentiated Services Field of the IPv6/IPv4 header (RFC2474).
