      Hi

      I am using MCX314A-BBCT  40G ConnectX -3 pro card. I am trying to change the card to RoCEv2 mode with INBOX driver. as per the below document

      But it is failing to change RoCE v2.

      RoCE v2 Considerations

       

      [root@xhdipsspdk1 ~]# echo "RoCE v2" > /sys/kernel/config/rdma_cm/mlx4_0/ports/2/default_roce_mode

      -bash: echo: write error: Invalid argument

       

      echo "RoCE V2" > /sys/kernel/config/rdma_cm/mlx4_0/ports/1/default_roce_mode

      -bash: echo: write error: Invalid argument

       

      Is it possible to change mode RoCEv2 with this card?

       

      Thanks

      Rama
