Can you tell me if the HAVE_MLX5DV_DR is defined? 2. can you please try adding device parameter ,dv_flow_en=0 and let me know if it works?

The command "sudo ./l2fwd -w 04:00.0,dv_flow_en=0 -- -p 0x1" worked perfectly for me. Thanks! Strangely on another server, exact the same server model and card, the card works with the flow option enabled (,dv_flow_en=1). ibv_devinfo shows exact the same fw_version vendor_id, board_id etc. Thanks, Sebastian On 05.01.20 08:09, Ori Kam wrote: Hi Sebastian, My Name is Ori and I'm part of Mellanox DPDK team.
