* Added MTU update in non Scattered Rx mode and enabled MTU of up to 9208
with UCS Software release 2.2 on 1300 series VICs.
* **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``
* **Added support for virtio on IBM POWER8.**
The ioports are mapped in memory when using Linux UIO.
