tc-skbedit

SKB editing action in tc(8)                                            Linux                                           SKB editing action in tc(8)

NAME

       skbedit - SKB editing action

SYNOPSIS

       tc ... action skbedit [ queue_mapping QUEUE_MAPPING ] [ priority PRIORITY ] [ mark MARK ] ptype PTYPE ]

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 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).

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
              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, otherhost, broadcast, multicast
