    RDMA write failing with RAE (AETH syndrome 96)

    ramakris

      First column is source and second column is destination.
      12.12.12.10 is Mellanox and 12.12.12.12 is our XRNIC target. Last but column is
      AETH syndrome.

       

      If you see for every write request going out there are 2
      incoming responses, out of them one with with RAE (AETH syndrome ‘d96) and next
      one is just positive ACK and there is not much timing difference between these
      responses only 15 us.

       

      This is protocol violation, Please suggest what would be wrong for this
