[Impact]

nVidia has requested the addition of this patch to support
some extended statistics from the Mellenox driver for DPDK.

[Test Plan]

/* download and install dpdk from github (issue do not reproduce with inbox dpdk) */
$ git clone https://github.com/mellanox/dpdk.org
$ cd dpdk.org/

/* install dependencies if needed */
$ apt-get install -y python3-pyelftools python-pyelftools
$ apt install meson

$ meson build-meson
$ ninja -C build-meson/

/* run dpdk-testpmd with mellanox HCA */

[Where problems could occur]

This patch extends devx interface and might affect any user space application
that uses rdma-core (which already has relevant patches), dpdk for instance.
