+* **Updated the mlx5 driver.**
+
+ The mlx5 driver was updated with changes including the following:
+
+ * Data path was refactored to bypass Verbs to improve RX and TX performance.
+ * Removed compilation parameters for inline send, ``MLX5_MAX_INLINE``, and
+ added command line parameter instead, ``txq_inline``.
+ * Improved TX scatter gather support:
+ Removed compilation parameter ``MLX5_PMD_SGE_WR_N``.
+ Scatter-gather elements is set to the maximum value the NIC supports.
+ Removed linearization logic, this decreases the memory consumption of the PMD.
+ * Improved jumbo frames support, by dynamically setting RX scatter gather elements
+ according to the MTU and mbuf size,
+ no need for compilation parameter ``MLX5_PMD_SGE_WR_N``
