usecases. Configuration happens via standard rawdev enq/deq operations. See
the :doc:`../rawdevs/cnxk_bphy` rawdev guide for more details on this driver.
-* **Added support for Marvell CN10K, CN9K, event Rx adapter.**
+* **Added support for Marvell CN10K, CN9K, event Rx/Tx adapter.**
- * Added Rx adapter support for event/cnxk when the ethernet device requested
+ * Added Rx/Tx adapter support for event/cnxk when the ethernet device requested
is net/cnxk.
* **Added cppc_cpufreq support to Power Management library.**
