Hi,
Please make sure you have follow the instructions in MLNX_DPDK QSG.
After OFED installation, configure options mlx4_core log_num_mgm_entry_size=-7 , run /etc/init.d/openibd restart
Compile DPDK (remove build dir before)
If you have old FW installed on you NIC, make sure new FW was installed during OFED installation - in this case you need to restart you server
Thanks
Olga
