API Changes
|
|
-----------
|
|
|
|
.. This section should contain API changes. Sample format:
|
|
|
|
* Add a short 1-2 sentence description of the API change. Use fixed width
|
|
quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past

|
|
=========================================================
|
|
|
|
* mbuf: The control mbuf API has been removed in v18.05. The impacted
|
|
functions and macros are:
|
|
|
|
- ``rte_ctrlmbuf_init()``
|
|
- ``rte_ctrlmbuf_alloc()``
|
|
- ``rte_ctrlmbuf_free()``
|
|
- ``rte_ctrlmbuf_data()``
|
|
- ``rte_ctrlmbuf_len()``
|
|
- ``rte_is_ctrlmbuf()``
|
|
- ``CTRL_MBUF_FLAG``
|
|
|
|
The packet mbuf API should be used as a replacement.
|
|
|
|
* meter: updated to accommodate configuration profiles.
|
|
|
|
The meter API is changed to support meter configuration profiles. The
|
|
configuration profile represents the set of configuration parameters
|
|
for a given meter object, such as the rates and sizes for the token
|
|
buckets. These configuration parameters were previously the part of meter
|
|
object internal data strcuture. The separation of the configuration
|
|
parameters from meter object data structure results in reducing its
|
|
memory footprint which helps in better cache utilization when large number
|
|
of meter objects are used.

|
|
