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 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 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 hexa‐
              decimal  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 automati‐
              cally  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 al‐
              low  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).
