13 The skbedit action allows to change a packet's associated meta data. It
14 complements the pedit action, which in turn allows to change parts of
15 the packet data itself.
16
17 The most unique feature of skbedit is its ability to decide over which
18 queue of an interface with multiple transmit queues the packet is to be
19 sent out. The number of available transmit queues is reflected by sysfs
20 entries within /sys/class/net/<interface>/queues with name tx-N (where
21 N is the actual queue number).
22
24 queue_mapping QUEUE_MAPPING
25 Override the packet's transmit queue. Useful when applied to
26 packets transmitted over MQ-capable network interfaces.
27 QUEUE_MAPPING is an unsigned 16bit value in decimal format.
28
29 priority PRIORITY
30 Override the packet classification decision. PRIORITY is either
31 root, none or a hexadecimal major class ID optionally followed
32 by a colon (:) and a hexadecimal minor class ID.
33
34 mark MARK[/MASK]
35 Change the packet's firewall mark value. MARK is an unsigned
36 32bit value in automatically detected format (i.e., prefix with
37 '0x' for hexadecimal interpretation, etc.). MASK defines the
38 32-bit mask selecting bits of mark value. Default is 0xffffffff.
39
40 ptype PTYPE
41 Override the packet's type. Useful for setting packet type to
42 host when needing to allow ingressing packets with the wrong MAC
43 address but correct IP address. PTYPE is one of: host, other‐
44 host, broadcast, multicast
45
46 inheritdsfield
47 Override the packet classification decision, and any value spec‐
48 ified with priority, using the information stored in the Differ‐
49 entiated Services Field of the IPv6/IPv4 header (RFC2474).
