This series of patches implements the mlx4-pmd with Tx data path that directly
access the device queues for transmitting packets, bypassing the ibverbs Tx
data path altogether.
Using this scheme allows the PMD to work with upstream rdma-core package
instead of the Mellanox OFED one without sacrificing Tx functionality.

These patches should be applied in the order listed below as each depends on
its predecessor to work.

This implementation allows rapid deployment of new features without the need to
update the underlying OFED.

This work depends on

        [dpdk-dev] [PATCH v1 00/48] net/mlx4: trim and refactor entire PMD
by Adrien Mazarguil

It had been built and tested using rdma-core-15-1 from
 https://github.com/linux-rdma/rdma-core
and kernel-ml-4.12.0-1.el7.elrepo.x86_64
