This diagram shows the data flow.
Tx:
-
Attach a buffer to a Queue in the i210 – transfer via DMA begins. “hpeAttachTransmitBufferSet”
-
Schedule a transmit time for timing accuracy with the timer. “hpeStartTransmitter”
-
Wait for transmit complete. “hpeWaitForTransmitComplete”
Rx:
-
Program the filter to select which Queue the receive data is routed into. “hpeSetReceiveQueueFilter”
-
Attach a receive buffer to each used Queue. “hpeAttachReceiveBufferSetToQueue”
-
Wait for receive complete. “hpeWaitForReceiveQueueComplete”
