Document new features added by the DPAA patch series:
- Offline (O/H) port device support (drv_oldev bus devarg)
- Rx/Tx taildrop threshold devargs (drv_rx_taildrop, drv_tx_taildrop)
- Fmcless Rx queue count devarg (drv_fmcless_rxq)
- DMA scatter-gather support and ERR050757 workaround

=======================================================
+* **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 Tx rate limiting API.**
+
+ Added ``rte_pmd_dpaa_port_set_rate_limit()`` to configure the
+ transmit rate limit (burst size and rate) on a DPAA port using the
+ FMAN port rate limiter.
+
+* **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 scatter-gather support and new device arguments.**
+
+ Added scatter-gather (SG) batching to the DPAA QDMA driver, enabled by
+ default, along with the ``dpaa_dma_sg_disable`` and
+ ``dpaa_dma_data_validation`` device arguments to disable SG batching and
+ to enable post-transfer data validation for debugging.
+ When the driver is built with ``RTE_DMA_DPAA_ERRATA_ERR050757``, the
+ source read type and stride are programmed to work around hardware
+ erratum ERR050757, and the ``dpaa_dma_pci_read_disable`` device argument
+ can be used to disable that programming.
