docs: Update supported QoS rule types
Since 1b8664f8e1
moves qos
constants to neutron-lib, here we updates the link.
Also this patch adds short description for
supported QoS rule types.

Supported QoS rule types
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Any plug-in or ml2 mechanism driver can claim support for some QoS rule types
|
||||
by providing a plug-in/driver class property called
|
||||
``supported_qos_rule_types`` that returns a list of strings that correspond
|
||||
to `QoS rule types
|
||||
<https://git.openstack.org/cgit/openstack/neutron/tree/neutron/services/qos/qos_consts.py>`_.
|
||||
QoS supported rule types are now available as ``VALID_RULE_TYPES`` in `QoS rule types
|
||||
<https://git.openstack.org/cgit/openstack/neutron-lib/tree/neutron_lib/services/qos/constants.py>`_:
|
||||
|
||||
* bandwidth_limit: Bandwidth limitations on networks or ports.
|
||||
|
||||
* dscp_marking: Marking network traffic with a DSCP value.
|
||||
|
||||
* minimum_bandwidth: Minimum bandwidth constraints on certain types of traffic.
|
||||
|
||||
|
||||
Any QoS driver can claim support for some QoS rule types
|
||||
by providing a driver property called
|
||||
``supported_rules``, the QoS driver manager will recalculate rule types
|
||||
dynamically that the QoS driver supports.
|
||||

||||
The following table shows the Networking back ends, QoS supported rules, and
|
||||
traffic directions (from the VM point of view).
