    Does MCX-312b (ConnectX-3 Pro) NOT support ibv_flow_spec_ipv4 rule?

    jsun

      For this NIC, ethtool reports it supports mlx4_flow_steering_ipv4 as below

      # ethtool --show-priv-flags ens2

      Private flags for ens2:

      blueflame                     : on

      mlx4_flow_steering_ethernet_l2: on

      mlx4_flow_steering_ipv4       : on

      mlx4_flow_steering_tcp        : on

      mlx4_flow_steering_udp        : on

      qcn_disable_32_14_4_e         : off

      rx-copy                       : off

      phv-bit                       : off

      rx-fcs                        : off

      rx-all                        : off

      mlx4_rss_xor_hash_function    : off

       

      But with ibv_query_device, it's reported NOT to support 'IBV_DEVICE_MANAGED_FLOW_STEERING.

       

      So, does this NIC actually support flow_steering_ipv4 in programming? or just support MAC--> QP flow steering rule?

       

      BTW, if ConnectX-3 Pro just support MAC--> QP flow steering rule, is it actually NOT able to support mcast receive acceleration

      ( kernel bypass) with libvma?

          Hi,

          What is the output of?

          #cat /etc/*release*

          #uname -a

          #ofed_info -s
