    Description

      An LNet user can allocate a large contiguous MD. That MD can have >
      LNET_MAX_IOV pages which causes some LNDs to assert on either niov
      argument passed to lnd_recv() or the value stored in
      lnet_msg::msg_niov. This is true even in cases where the actual
      transfer size is <= LNET_MTU and will not exceed limits in the LNDs.
