This chapter describes the limited host-based transmission functionality, which enables DMA-based transmission of frames located in a host buffer in the server application memory.
The limited TX functionality consumes a significant amount of CPU resources if large amounts of data are transmitted. The performance depends on the server system. Line rate cannot be obtained. For 64-byte frames the throughput is around 40 Mbit/s.
The limited TX functionality is activated using the NT_NetTxOpen function (see DN-0449).
