    IB/mlx5: Collect signature error completion · d5436ba0
    Sagi Grimberg 提交于
    This commit takes care of the generated signature error CQE generated
    by the HW (if happened).  The underlying mlx5 driver will handle
    signature error completions and will mark the relevant memory region
    as dirty.
    
    Once the consumer gets the completion for the transaction, it must
    check for signature errors on signature memory region using a new
    lightweight verb ib_check_mr_status().
    
    In case the user doesn't check for signature error (i.e. doesn't call
    ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the
    memory region cannot be used for another signature operation
    (REG_SIG_MR work request will fail).
