^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) Maximum number of segments that the frontend will negotiate
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) with the backend for indirect descriptors. The default value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) is 32 - higher value means more potential throughput but more
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) memory usage. The backend picks the minimum of the frontend
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) and its default backend value.
