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).
