I understand you do not see anything like the following lines while DPDK is
being compiled?

 == BUILD drivers/net/mlx4
   CC mlx4.o
   AR librte_pmd_mlx4.a
   INSTALL-LIB librte_pmd_mlx4.a

If you don't, something is wrong in your .config, perhaps you haven't
edited the right one? Depending on your target, DPDK may generate another
with default options in an unexpected place and use it instead of your own.

Otherwise, I suggest following Olga's advice, your ports may not be in the
right mode (IB instead of Ethernet), or you're using the wrong kernel
modules in which case mlx4 usually complains during startup.

This is only a guess, please provide compilation, program (testpmd?) startup
logs and the related command line if it still doesn't work.
