It complements the +.B pedit +action, which in turn allows one to change parts of the packet data itself. + +The most unique feature of +.B 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 +.I /sys/class/net/<interface>/queues +with name +.I tx-N +(where +.I N +is the actual queue number). +.SH OPTIONS +.TP +.BI queue_mapping " QUEUE_MAPPING" +Override the packet's transmit queue. Useful when applied to packets transmitted +over MQ-capable network interfaces. +.I QUEUE_MAPPING +is an unsigned 16bit value in decimal format. +.TP +.BI priority " PRIORITY" +Override the packet classification decision. +.I PRIORITY +is either +.BR root ", " none +or a hexadecimal major class ID optionally followed by a colon +.RB ( : ) +and a hexadecimal minor class ID. +.TP +.BI mark " MARK\fR[\fB/\fIMASK]" +Change the packet's firewall mark value. +.I MARK +is an unsigned 32bit value in automatically detected format (i.e., prefix with +.RB ' 0x ' +for hexadecimal interpretation, etc.). +.I MASK +defines the 32-bit mask selecting bits of mark value. Default is 0xffffffff. +.TP +.BI 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. +.I PTYPE +is one of: host, otherhost, broadcast, multicast +.TP +.BI inheritdsfield +Override the packet classification decision, and any value specified with +.BR priority ", " +using the information stored in the Differentiated Services Field of the +IPv6/IPv4 header (RFC2474). +.SH SEE ALSO +.BR tc (8), +.BR tc-pedit (8) |
