Since the get_rate() code incorrectly interpreted bare number, the behavior is not the same as man page and comment described. We need to change the man page and comment for compatible with the existing usage by scripts.

Because we use the high 16 bits of tcm_info to pass prio value to kernel, thus it's range would be [0, 0xffff], without validation in tc when user pass a lager(>65535) priority, the actual priority set in kernel would confuse the user. So, add a validation to ensure prio in the range.

<groff: tc.8>:51: warning: total indent cannot be negative <groff: tc.8>:57: warning: escape character ignored before `i' ********************* Space at end of line removed General considerations a) Manuals should usually only be left justified. Use ".ad l" as the first regular command. b) Each sentence should begin on a new line. The conventions about the amount of space between sentences are different. This also makes a check on the number of space characters between words easier. c) Separate numbers from units with a (no-break) space. A no-break space can be code 0xA0, "\ " (\<space>), or "\~" (groff). d) Use macros "TS/TE" for tables with more than two columns. Then use '\" t as the first line in the source to tell "man" to use the "tbl" preprocessor. e) Protect last period (full stop) in abbreviations with "\&", if it is or might be (through new formatting of source) at the end of line, if it is also not an end of sentence. ********************* Originally filed at: http://bugs.debian.org/674704Signed-off-by:

Adds support for parsing IPv6 addresses to the parameters local and remote in the l2tp commands. Requires netlink attributes L2TP_ATTR_IP6_SADDR and L2TP_ATTR_IP6_DADDR, added in a required kernel patch already submitted to netdev. Also enables printing of IPv6 addresses returned by the L2TP_CMD_TUNNEL_GET request. Signed-off-by:

Fair Queue Codel packet scheduler Principles : - Packets are classified (internal classifier or external) on flows. - This is a Stochastic model (as we use a hash, several flows might be hashed on same slot) - Each flow has a CoDel managed queue. - Flows are linked onto two (Round Robin) lists, so that new flows have priority on old ones. - For a given flow, packets are not reordered (CoDel uses a FIFO) - head drops only. - ECN capability is on by default. - Very low memory footprint (64 bytes per flow) tc qdisc ... fq_codel [ limit PACKETS ] [ flows number ] [ target TIME ] [ interval TIME ] [ noecn ] [ quantum BYTES ] Signed-off-by:

An implementation of CoDel AQM, from Kathleen Nichols and Van Jacobson. http://queue.acm.org/detail.cfm?id=2209336 This AQM main input is no longer queue size in bytes or packets, but the delay packets stay in (FIFO) queue. As we don't have infinite memory, we still can drop packets in enqueue() in case of massive load, but mean of CoDel is to drop packets in dequeue(), using a control law based on two simple parameters : target : target sojourn time (default 5ms) interval : width of moving time window (default 100ms) Selected packets are dropped, unless ECN is enabled and packets can get ECN mark instead. Usage: tc qdisc ... codel [ limit PACKETS ] [ target TIME ] [ interval TIME ] [ ecn ] qdisc codel 10: parent 1:1 limit 2000p target 3.0ms interval 60.0ms ecn Sent 13347099587 bytes 8815805 pkt (dropped 0, overlimits 0 requeues 0) rate 202365Kbit 16708pps backlog 113550b 75p requeues 0 count 116 lastcount 98 ldelay 4.3ms dropping drop_next 816us maxpacket 1514 ecn_mark 84399 drop_overlimit 0 CoDel must be seen as a base module, and should be used keeping in mind there is still a FIFO queue. So a typical setup will probably need a hierarchy of several qdiscs and packet classifiers to be able to meet whatever constraints a user might have. One possible example would be to use fq_codel, which combines Fair Queueing and CoDel, in replacement of sfq / sfq_red. Signed-off-by:

Reported by Robert Henney: > the 'ip' man page does not mention the command "del" at all but does > claim, "As a rule, it is possible to add, delete and show (or list ) objects". > however, 'ip' does not always recognize "delete" as a commend. > > robh@debian:~$ ip tunnel delete > Command "delete" is unknown, try "ip tunnel help". Lets use "delete" in all calls to matches() for consistency. This will make both "del" and "delete" work everywhere. Signed-off-by:

Reported by Ivan Vilata i Balaguer <ivan@selidor.net> found that the description of the `ip link add` command in the manpage is outdated regarding the compulsory `link DEVICE` option. For instance, `ip link help` says: Usage: ip link add [link DEV] [ name ] NAME ... But the manpage still says: ip link add link DEVICE [ name ] NAME (Trying to provide a `link` option e.g. under an LXC container can frustrate the creation of dummy devices which don't need an actual device.) The syntax of the "ip link help" output was fixed in commit "iproute2: Fix usage and man page for 'ip link'" (a22e9295). This updates the manpage to mark "link DEVICE" as an optional argument there as well. http://bugs.debian.org/673171Signed-off-by:

Add a new netlink attribute type to the dump request to allow filtering of the information returned for the respective matching interfaces. At this time the only filter defined is to request virtual function (VF) device info for interfaces that attached VFs.
