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).
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.
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.
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.).
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
