Protocol Driver Send and Receive Operations
Protocol drivers originate send requests and handle the receive indications of underlying drivers. In a single function call, NDIS protocol drivers can send multiple NET_BUFFER_LIST structures with multiple NET_BUFFER structures on each NET_BUFFER_LIST structure. In the receive path, protocol drivers can receive a list of NET_BUFFER_LIST structures.
Protocol drivers must manage send buffer pools. Proper management of such pools requires preallocation of sufficient buffer space to optimize system performance.
