     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 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
