      =======================================================
 
+* **Added NXP DPAA offline (O/H) port device support.**
+
+  Added support for the DPAA Offline/Host-command (O/H) port, allowing
+  a DPDK application to use an offline port for packet processing.
+  The feature is selected through the ``drv_oldev`` bus device argument.
+
+* **Added NXP DPAA Rx/Tx taildrop threshold device arguments.**
+
+  Added ``drv_rx_taildrop`` and ``drv_tx_taildrop`` device arguments
+  to configure per-port frame queue taildrop congestion thresholds
+  at device probe time.
+
+* **Added NXP DPAA fmcless Rx queue count device argument.**
+
+  Added ``drv_fmcless_rxq`` device argument to set the number of
+  Rx queues when running without FMC configuration.
+
+* **Added NXP DPAA shared MAC kernel interface name device argument.**
+
+  Added ``drv_sh_if_name`` device argument to provide the Linux kernel
+  interface name of a shared MAC interface when it differs from the
+  ``fmX-macY`` style name used by DPDK.
+
+* **Added NXP DPAA DMA device arguments for runtime configuration.**
+
+  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.
