Tx configuration : Per port Tx queue. Multiple Tx host buffers to the same egress port will be merged round-robin.
Segment timeout : Auto-detected to match the time it takes to receive 1MB data.
Poll interval : The driver will poll for new data every 1ms.
Host buffer layout: The host buffer is scatter-gather based.
If multiple streams are utilizing the same egress port they must run with TxNow=True otherwise the time-stamps in the packets will cause jumps in time and result in stalls in the transmit engine.
