Hi Shahaf,
1. Can you please explain what is the meaning of upstream-libs?
2. We use Ubuntu 12.04. so if we would like to stay with it, and use MLNX_OFED-4.0, which latest DPDK version should be used?
Thanks,
Asaf

DPDK version 18.05 supports only upstream-libs (rdma-core).

Yes MLNX_OFED-4.0 is too old for upstream libs. You should use MLNX_OFED-4.2 and above.
Or alternatively use an older DPDK version (not recommended).
