Data Flow

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”
