[dpdk-dev] [PATCH 1/3] app/testpmd: metering and policing CLI clean up

[dpdk-dev] [PATCH 1/3] app/testpmd: metering and policing CLI clean up

[Jasvinder Singh]

This patch updates the metering and policing CLIs as follows:
- change name of set port meter CLI to create port meter and add meter
  enable option, dscp table entries arguments, action mask, policer actions
  and previous meter color option as an input color
- set the right metering algorithm in add meter profile CLIs related to
  srtcm(rfc2697) and trtcm(rfc2698,rfc4115)
- change clear flag type from uint32_t to string in show meter stats CLI

[dpdk-dev] [PATCH 2/3] app/testpmd: add CLI for metering and policing API

[Jasvinder Singh]

Add following CLIs to testpmd application;
- show port metering and policing capabilities.
- enable/disable meter of the MTR object.
- update the MTR object dscp table entries.

+Traffic Metering and Policing
+-----------------------------
+
+The following section shows functions for configuring traffic metering and
+policing on the ethernet device through the use of generic ethdev API.
+
+show port traffic management capability
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Show traffic metering and policing capability of the port::
+
+   testpmd> show port meter cap (port_id)
+
+add port meter profile (srTCM rfc2967)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Add meter profile (srTCM rfc2697) to the ethernet device::
+
+   testpmd> add port meter profile srtcm_rfc2697 (port_id) (profile_id) \
+   (cir) (cbs) (ebs)
+
+where:
+
+* ``profile_id``: ID for the meter profile.
+* ``cir``: Committed Information Rate (CIR) (bytes/second).
+* ``cbs``: Committed Burst Size (CBS) (bytes).
+* ``ebs``: Excess Burst Size (EBS) (bytes).
+
+add port meter profile (trTCM rfc2968)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Add meter profile (srTCM rfc2698) to the ethernet device::
+
+   testpmd> add port meter profile trtcm_rfc2698 (port_id) (profile_id) \
+   (cir) (pir) (cbs) (pbs)
+
+where:
+
+* ``profile_id``: ID for the meter profile.
+* ``cir``: Committed information rate (bytes/second).
+* ``pir``: Peak information rate (bytes/second).
+* ``cbs``: Committed burst size (bytes).
+* ``pbs``: Peak burst size (bytes).
+

+* ``cbs``: Committed burst size (bytes).
+* ``ebs``: Excess burst size (bytes).
+
+delete port meter profile
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Delete meter profile from the ethernet device::
+
+   testpmd> del port meter profile (port_id) (profile_id)
+
+create port meter
+~~~~~~~~~~~~~~~~~
+
+Create new meter object for the ethernet device::
+
+   testpmd> create port meter (port_id) (mtr_id) (profile_id) \
+   (meter_enable) (g_action) (y_action) (r_action) (stats_mask) (shared) \
+   (use_pre_meter_color) [(dscp_tbl_entry0) (dscp_tbl_entry1)...\
+   (dscp_tbl_entry63)]
+
+where:
+
+* ``mtr_id``: meter object ID.
+* ``profile_id``: ID for the meter profile.
+* ``meter_enable``: When this parameter has a non-zero value, the meter object
+  gets enabled at the time of creation, otherwise remains disabled.
+* ``g_action``: Policer action for the packet with green color.
+* ``y_action``: Policer action for the packet with yellow color.
+* ``r_action``: Policer action for the packet with red color.
+* ``stats_mask``: Mask of statistics counter types to be enabled for the
+  meter object.
+* ``shared``:  When this parameter has a non-zero value, the meter object is
+  shared by multiple flows. Otherwise, meter object is used by single flow.
+* ``use_pre_meter_color``: When this parameter has a non-zero value, the
+  input color for the current meter object is determined by the latest meter
+  object in the same flow. Otherwise, the current meter object uses the
+  *dscp_table* to determine the input color.
+* ``dscp_tbl_entryx``: DSCP table entry x providing meter providing input
+  color, 0 <= x <= 63.
+
+enable port meter

+
+Disable meter for the ethernet device::
+
+   testpmd> disable port meter (port_id) (mtr_id)
+
+delete port meter
+~~~~~~~~~~~~~~~~~
+
+Delete meter for the ethernet device::

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+Set meter policer action for the ethernet device::
+
+   testpmd> set port meter policer action (port_id) (mtr_id) (action_mask) \
+   (action0) [(action1) (action1)]
+
+where:
+
+* ``action_mask``: Bit mask indicating which policer actions need to be
+  updated. One or more policer actions can be updated in a single function
+  invocation. To update the policer action associated with color C, bit
+  (1 << C) needs to be set in *action_mask* and element at position C
+  in the *actions* array needs to be valid.
+* ``actionx``: Policer action for the color x,
+  RTE_MTR_GREEN <= x < RTE_MTR_COLORS
+
+set port meter stats mask
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Set meter stats mask for the ethernet device::
+
+   testpmd> set port meter stats mask (port_id) (mtr_id) (stats_mask)

Note, there is a devtools/check-git-log.sh warning on the commit subject. Maybe use
something like this instead, if you update the patchset, or the maintainer can fix
inline:

Is that meaning the size dscp table must be 64, can it be less than 64?

The DSCP field is represented by 6 bits in the byte long TOS field of the IP header. Therefore, DSCP table should be have 64 entries for the packets classification.
