<para>
Each qdisc can be specified by the following attributes:
</para>
<variablelist>
<varlistentry>
<term><varname>handle HANDLE</varname></term>
<listitem>
<para>
specifies the qdisc handle. A qdisc, which potentially can have children, gets
assigned a major number, called a 'handle', leaving the minor number namespace
available for classes. The handle is expressed as '10:'. It is customary to
explicitly assign a handle to qdiscs expected to have children.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>parent HANDLE</varname></term>

<term><varname>KIND</varname></term>
<listitem>
<para>
this is the qdisc kind. NetworkManager currently supports the
following kinds: fq_codel, sfq, tbf. Each qdisc kind has a
different set of parameters, described below. There are also some
kinds like pfifo, pfifo_fast, prio supported by NetworkManager
but their parameters are not supported by NetworkManager.

<variablelist>
<varlistentry>
<term><varname>limit U32</varname></term>
<listitem>
<para>
the hard limit on the real queue size.  When this limit is
reached, incoming packets are dropped. Default is 10240 packets.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>memory_limit U32</varname></term>
<listitem>
<para>
sets a limit on the total number of bytes that can be queued in
this FQ-CoDel instance. The lower of the packet limit of the
limit parameter and the memory limit will be enforced. Default is
32 MB.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>flows U32</varname></term>
<listitem>
<para>
the number of flows into which the incoming packets are
classified. Due to the stochastic nature of hashing, multiple
flows may end up being hashed into the same slot. Newer flows
have priority over older ones. This parameter can be set only at
load time since memory has to be allocated for the hash table.
Default value is 1024.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>target U32</varname></term>
<listitem>
<para>
the acceptable minimum standing/persistent queue delay. This minimum
delay is identified by tracking the local minimum queue delay that packets
experience. The unit of measurement is microsecond(us). Default value is 5ms.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>interval U32</varname></term>
<listitem>
<para>
used to ensure that the measured minimum delay does not become too stale.
The minimum delay must be experienced in the last epoch of length .B
interval.  It should be set on the order of the worst-case RTT
through the bottleneck to give endpoints sufficient time to
react. Default value is 100ms.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>quantum U32</varname></term>
<listitem>
<para>
the number of bytes used as 'deficit' in the fair queuing
algorithm. Default is set to 1514 bytes which corresponds to the
Ethernet MTU plus the hardware header length of 14 bytes.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>ecn BOOL</varname></term>

</listitem>
</varlistentry>
<varlistentry>
<term><varname>ce_threshold U32</varname></term>
<listitem>
<para>
sets a threshold above which all packets are marked with ECN
Congestion Experienced. This is useful for DCTCP-style congestion
control algorithms that require marking at very shallow queueing
thresholds.

</para>
<variablelist>
<varlistentry>
<term><varname>divisor U32</varname></term>
<listitem>
<para>
can be used to set a different hash table size, available
from kernel 2.6.39 onwards.  The specified divisor must be
a power of two and cannot be larger than 65536.  Default
value: 1024.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>limit U32</varname></term>
<listitem>
<para>
Upper limit of the SFQ. Can be used to reduce the default
length of 127 packets.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>depth U32</varname></term>
<listitem>
<para>
Limit of packets per flow. Default to
127 and can be lowered.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>perturb_period U32</varname></term>
<listitem>
<para>
Interval in seconds for queue algorithm perturbation.
Defaults to 0, which means that no perturbation occurs. Do
not set too low for each perturbation may cause some
packet reordering or losses. Advised value: 60 This value
has no effect when external flow classification is used.
Its better to increase divisor value to lower risk of hash
collisions.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>quantum U32</varname></term>
<listitem>
<para>
Amount of bytes a flow is allowed to dequeue during a

the interface which is also the advised value and the
minimum value.
</para>

Parameters for 'tbf':
</para>
<variablelist>
<varlistentry>
<term><varname>rate U64</varname></term>
<listitem>
<para>
Bandwidth or rate.  These parameters accept a floating
point number, possibly followed by either a unit (both SI
and IEC units supported), or a float followed by a percent
character to specify the rate as a percentage of the
device's speed.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>burst U32</varname></term>
<listitem>
<para>
Also known as buffer or maxburst.  Size of the bucket, in
bytes. This is the maximum amount of bytes that tokens can
be available for instantaneously.  In general, larger
shaping rates require a larger buffer. For 10mbit/s on
Intel, you need at least 10kbyte buffer if you want to
reach your configured rate!
</para>
<para>
If your buffer is too small, packets may be dropped
because more tokens arrive per timer tick than fit in your
bucket.  The minimum buffer size can be calculated by
dividing the rate by HZ.
</para>
<para>
Token usage calculations are performed using a table which
by default has a resolution of 8 packets.  This resolution
can be changed by specifying the cell size with the burst.
For example, to specify a 6000 byte buffer with a 16 byte
cell size, set a burst of 6000/16. You will probably never
have to set this. Must be an integral power of 2.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><varname>limit U32</varname></term>
<listitem>
<para>
Limit is the number of bytes that can be queued waiting
for tokens to become available.
</para>

</varlistentry>
<varlistentry>
<term><varname>latency U32</varname></term>
<listitem>
<para>
specifies the maximum amount of time a packet can
sit in the TBF. The latency calculation takes into account
the size of the bucket, the rate and possibly the peakrate
(if set). The latency and limit are mutually exclusive.
