Add a single "Updated NXP DPAA drivers" entry for the changes made by
this series, with one sub-bullet each:

  - FMCLESS mode now defaults to the maximum Rx queues per port instead
    of the number of lcores
  - the fmlib create_device() and get_device_id() helpers are renamed
    with an fm_ prefix
  - DMA devargs to control the existing scatter-gather batching, data
    validation and ERR050757 programming at runtime
    (dpaa_dma_sg_disable, dpaa_dma_data_validation,
    dpaa_dma_pci_read_disable)

   * Added Tx pause support for the ENETC4 VF via Rx congestion mode.
   * Added WRR Tx scheduler devarg (``enetc4_txq_wrr``) for ENETC4 VF ring weights.
 
+* **Updated NXP DPAA drivers.**
+
+  * Changed the default number of Rx queues in FMCLESS mode to the maximum
+    supported per port instead of the number of lcores, because several
+    queues may be processed on the same core.
+  * Renamed the fmlib ``create_device()`` and ``get_device_id()`` helpers to
+    ``fm_create_device()`` and ``fm_get_device_id()`` to avoid clashing with
+    other drivers when DPDK is linked statically.
+  * Added device arguments to the DPAA QDMA driver to control existing
+    driver behaviour at runtime: ``dpaa_dma_sg_disable`` submits each
+    descriptor as an individual single-entry transfer instead of the
+    default scatter-gather batching, ``dpaa_dma_data_validation`` enables
+    the post-transfer data validation helper for debugging, and, when the
+    driver is built with ``RTE_DMA_DPAA_ERRATA_ERR050757``,
+    ``dpaa_dma_pci_read_disable`` skips the ERR050757 source
+    read-transaction programming.
+
 * **Updated Solarflare network driver.**
 
   * Added VF support on AMD Solarflare X45xx adapters.
