MLX4 poll mode driver library
=============================
``CONFIG_RTE_BUILD_SHARED_LIB`` disabled) and they won't show up as
missing with ``ldd(1)``.
+ It works by moving these dependencies to a purpose-built rdma-core "glue"
+ plug-in which must either be installed in a directory whose name is based
+ on ``CONFIG_RTE_EAL_PMD_PATH`` suffixed with ``-glue`` if set, or in a
+ standard location for the dynamic linker (e.g. ``/lib``) if left to the
+ default empty string (``""``).
+
This option has no performance impact.
- ``CONFIG_RTE_LIBRTE_MLX4_DEBUG`` (default **n**)
This value is always 1 for RX queues since they use a single MP.

+ A list of directories in which to search for the rdma-core "glue" plug-in,
+ separated by colons or semi-colons.
+
+ Only matters when compiled with ``CONFIG_RTE_LIBRTE_MLX4_DLOPEN_DEPS``
+ enabled and most useful when ``CONFIG_RTE_EAL_PMD_PATH`` is also set,
+ since ``LD_LIBRARY_PATH`` has no effect in this case.
