The current driver requires v16. It will not work or build with
the older version (as in Debian stable). Note: libmlx5 is rolled
into rdma-core in current versions.
Mlx4 probably requires similar documentation update.

This driver relies on external libraries and kernel drivers for resources

+allocations and initialization. The following packages come from the

- **libibverbs**
User space Verbs framework used by librte_pmd_mlx5. This library provides
- a generic interface between the kernel and low-level user space drivers

+ a generic interface between the kernel and low-level user space drivers.
It allows slow and privileged operations (context initialization, hardware
resources allocations) to be managed by the kernel and fast operations to
never leave user space.
-- **libmlx5**
+ The development package (libibverbs-dev or libibverbs-devel) are necessary

- Low-level user space driver library for Mellanox ConnectX-4/ConnectX-5

+- **rdma-core**
