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).
