 5Description:
 6                Maximum number of segments that the frontend will negotiate
 7                with the backend for indirect descriptors. The default value
 8                is 32 - higher value means more potential throughput but more
 9                memory usage. The backend picks the minimum of the frontend
10                and its default backend value.
