Pablo de Lara 2925e0c190 cryptodev: define value for unlimited sessions
Currently, the info structure contains the maximum number
of sessions that a device can manage.
This field was useful when the session mempool was created inside
each device, but now it is created at the application level.

Most PMDs do not have a limitation on the sessions managed,
but a few do, therefore this field must remain in the structure.
However, a new value, 0, can be used to indicate that
a device does not have an actual maximum of sessions.

New Features
------------
.. This section should contain new features added in this release.
Sample format:
* **Add a title in the past tense with a full stop.**
Add a short 1-2 sentence description in the past tense.
The description should be enough to allow someone scanning
the release notes to understand the new feature.
If the feature adds a lot of sub-features you can use a bullet list
like this:
* Added feature foo to do something.
* Enhanced feature bar to do something else.
Refer to the previous release notes for examples.

Also, make sure to start the actual text at the margin.
=========================================================
* **Added Flow API support for CXGBE PMD.**
Flow API support has been added to CXGBE Poll Mode Driver to offload
flows to Chelsio T5/T6 NICs.
* **Added ixgbe preferred Rx/Tx parameters.**
Rather than applications providing explicit Rx and Tx parameters such as
queue and burst sizes, they can request that the EAL instead uses preferred
values provided by the PMD, falling back to defaults within the EAL if the
PMD does not provide any. The provision of such tuned values now includes
the ixgbe PMD.
* **Added descriptor status check support for fm10k.**
``rte_eth_rx_descritpr_status`` and ``rte_eth_tx_descriptor_status``
are supported by fm10K.
* **Updated the enic driver.**
* Add support for mbuf fast free offload.
* Add low cycle count Tx handler for no-offload Tx (except mbuf fast free).
* Add low cycle count Rx handler for non-scattered Rx.
* Minor performance improvements to scattered Rx handler.
* Add handlers to add/delete VxLAN port number.
* Add devarg to specify ingress VLAN rewrite mode.
API Changes
-----------
.. This section should contain API changes. Sample format:
* Add a short 1-2 sentence description of the API change.

* cryptodev: In struct ``struct rte_cryptodev_info``, field ``rte_pci_device *pci_dev``
has been replaced with field ``struct rte_device *device``.
Value 0 is accepted in ``sym.max_nb_sessions``, meaning that a device
supports an unlimited number of sessions.
* compressdev: Feature flag ``RTE_COMP_FF_MBUF_SCATTER_GATHER`` is
replaced with the following more explicit flags:
- ``RTE_COMP_FF_OOP_SGL_IN_SGL_OUT``
- ``RTE_COMP_FF_OOP_SGL_IN_LB_OUT``
- ``RTE_COMP_FF_OOP_LB_IN_SGL_OUT``
