Since band number counts from zero thus band must be little than
opt.bands.

Parameter priomap use blank instead of comma to separate bands,

2: Reorder the SEE ALSO section to make the order alphabetical

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.

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 ]

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.

Lets use "delete" in all calls to matches() for consistency. This will

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.

Hi,

I've attached a trivial patch for iproute2 to allow naming interfaces
created with "ip l2tp add session".

I believe patches should go through the netdev mailing list but this
patch is so small I figured that would just add noise. Hope that's OK.

Originally I thought I would need a bigger patch and was going to take a
stab at implementing something like

ip l2tp add tunnel L2TP_TUNNEL_ARGS
ip link add name NAME  [ LINK_OPTS ] type l2tp L2TP_SESSION_ARGS

(a better interface IMHO) but all the code was there already, all that I
needed to add was option parsing.

Thanks,

João Valverde
