4.4.4.1. Transmit Path

The MAC TX uses the default preamble bytes as defined in the IEEE802.3 specification during frame encapsulation (i.e., "packetization") process.
Note: All other modes of operations such as CRC calculation, DIC, and throughput rate must not be affected by the mode. The hardware implication is, for instance, CRC calculation must only start on the third data phase (of avalon_st_tx_data[31:0]) onwards.
