NAME
skbedit - SKB editing action
SYNOPSIS
tc ... action skbedit [ queue_mapping QUEUE_MAPPING ] [ priority PRIORITY ] [ mark MARK ]
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 net‐
work 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.).
