8 Use proper spelling, capitalization and punctuation in all sections.
10 Variable and config names should be quoted as fixed width text:

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

42 =========================================================
44 * **Added PMD-recommended Tx and Rx parameters**
46 Applications can now query drivers for device-tuned values of
47 ring sizes, burst sizes, and number of queues.
49 * **Added RSS hash and key update to CXGBE PMD.**
51 Support to update RSS hash and key has been added to CXGBE PMD.
53 * **Added CXGBE VF PMD.**
55 CXGBE VF Poll Mode Driver has been added to run DPDK over Chelsio
56 T5/T6 NIC VF instances.
58 * **Updated Solarflare network PMD.**
60 Updated the sfc_efx driver including the following changes:
62 * Added support for Solarflare XtremeScale X2xxx family adapters.
63 * Added support for NVGRE, VXLAN and GENEVE filters in flow API.
64 * Added support for DROP action in flow API.
66 * **Added Ethernet poll mode driver for AMD XGBE devices.**
68 Added the new ``axgbe`` ethernet poll mode driver for AMD XGBE devices.
69 See the :doc:`../nics/axgbe` nic driver guide for more details on this
72 * **Added crypto workload support to vhost library.**
74 New APIs are introduced in vhost library to enable virtio crypto support
75 including session creation/deletion handling and translating virtio-crypto
76 request into DPDK crypto operations. A sample application is also introduced.
78 * **Added device event monitor framework.**
80 Added a general device event monitor framework at EAL, for device dynamic management.
81 Such as device hotplug awareness and actions adopted accordingly. The list of new APIs:
83 * ``rte_dev_event_monitor_start`` and ``rte_dev_event_monitor_stop`` are for
84 the event monitor enable and disable.
85 * ``rte_dev_event_callback_register`` and ``rte_dev_event_callback_unregister``
86 are for the user's callbacks register and unregister.
88 Linux uevent is supported as backend of this device event notification framework.
94 .. This section should contain API changes. Sample format:
96 * Add a short 1-2 sentence description of the API change. Use fixed width
97 quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past

102 =========================================================
104 * mbuf: The control mbuf API has been removed in v18.05. The impacted
105 functions and macros are:
107 - ``rte_ctrlmbuf_init()``
108 - ``rte_ctrlmbuf_alloc()``
109 - ``rte_ctrlmbuf_free()``
110 - ``rte_ctrlmbuf_data()``
111 - ``rte_ctrlmbuf_len()``
112 - ``rte_is_ctrlmbuf()``
115 The packet mbuf API should be used as a replacement.
117 * meter: updated to accommodate configuration profiles.
119 The meter API is changed to support meter configuration profiles. The
120 configuration profile represents the set of configuration parameters
121 for a given meter object, such as the rates and sizes for the token
122 buckets. These configuration parameters were previously the part of meter
123 object internal data strcuture. The separation of the configuration
124 parameters from meter object data structure results in reducing its
125 memory footprint which helps in better cache utilization when large number
126 of meter objects are used.
128 * ethdev, in struct ``struct rte_eth_dev_info``, field ``rte_pci_device *pci_dev``
129 replaced with field ``struct rte_device *device``.
131 * **Changes to semantics of rte_eth_dev_configure() parameters.**
133 If both the ``nb_rx_q`` and ``nb_tx_q`` parameters are zero,
134 ``rte_eth_dev_configure`` will now use PMD-recommended queue sizes, or if
135 recommendations are not provided by the PMD the function will use ethdev
136 fall-back values. Previously setting both of the parameters to zero would
137 have resulted in ``-EINVAL`` being returned.
139 * **Changes to semantics of rte_eth_rx_queue_setup() parameters.**
141 If the ``nb_rx_desc`` parameter is zero, ``rte_eth_rx_queue_setup`` will
142 now use the PMD-recommended Rx ring size, or in the case where the PMD
143 does not provide a recommendation, will use an ethdev-provided
144 fall-back value. Previously, setting ``nb_rx_desc`` to zero would have
145 resulted in an error.
147 * **Changes to semantics of rte_eth_tx_queue_setup() parameters.**
149 If the ``nb_tx_desc`` parameter is zero, ``rte_eth_tx_queue_setup`` will
150 now use the PMD-recommended Tx ring size, or in the case where the PMD
151 does not provide a recoomendation, will use an ethdev-provided
152 fall-back value. Previously, setting ``nb_tx_desc`` to zero would have
153 resulted in an error.
159 .. This section should contain ABI changes. Sample format:
161 * Add a short 1-2 sentence description of the ABI change that was announced
162 in the previous releases and made in this release. Use fixed width quotes
163 for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.

166 Also, make sure to start the actual text at the margin.
167 =========================================================
169 * **Additional fields in rte_eth_dev_info.**
171 The ``rte_eth_dev_info`` structure has had two extra entries appended to the
172 end of it: ``default_rxportconf`` and ``default_txportconf``. Each of these
173 in turn are ``rte_eth_dev_portconf`` structures containing three fields of
174 type ``uint16_t``: ``burst_size``, ``ring_size``, and ``nb_queues``. These
175 are parameter values recommended for use by the PMD.
180 .. This section should contain removed items in this release. Sample format:
182 * Add a short 1-2 sentence description of the removed item in the past
185 This section is a comment. Do not overwrite or remove it.

193 .. This section should contain new known issues in this release. Sample format:
195 * **Add title in present tense with full stop.**
197 Add a short 1-2 sentence description of the known issue in the present
198 tense. Add information on any known workarounds.
