skbedit - SKB editing action
tc ... action skbedit [ queue_mapping QUEUE_MAPPING ] [ priority
PRIORITY ] [ mark MARK[/MASK] ] [ ptype PTYPE ] [
inheritdsfield ]
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 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).
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).
