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 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).
