4.1.2.1. IP Core Preamble Processing

If you turn on Enable preamble passthrough in the parameter editor, the RX MAC forwards preamble bytes. The TX MAC requires the preamble bytes to be included in the frames at the Avalon® Streaming interface.

Note that a single parameter in the Low Latency E-Tile 40G Ethernet parameter editor turns on both RX and TX preamble passthrough.
