In v17.05 MLX5 PMD is still relying on libibverbs and libmlx5, the way
Those options you used are necessary to select in their package the
installation of libverbs,libmlx5 or rdma-core.
Doing this you have selected rdma-core which is not supported in v17.05
DPDK version.

You need to install Mellanox OFED without those two options to select
libibverbs, libmlx5 to make it work.
