58c2ecf20Sopenharmony_ciDescription:
68c2ecf20Sopenharmony_ci                Maximum number of segments that the frontend will negotiate
78c2ecf20Sopenharmony_ci                with the backend for indirect descriptors. The default value
88c2ecf20Sopenharmony_ci                is 32 - higher value means more potential throughput but more
98c2ecf20Sopenharmony_ci                memory usage. The backend picks the minimum of the frontend
108c2ecf20Sopenharmony_ci                and its default backend value.
