       skbedit - SKB editing action

       tc ... action skbedit [ queue_mapping QUEUE_MAPPING ] [ priority PRIOR-
               ITY ] [ mark MARK ] ptype PTYPE ]

       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).

       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,  other-
              host, broadcast, multicast
