Verilog Ethernet: Work-in-Progress 100BASE-TX PHY

100mbit ethernet is very common in industrial use. It is also more robust EMI/RFI and easier to get past EMC certifications.

And 10Base is evolving, not going a way. Base-T1L spec got recently released. It does full-duplex 10mbit over a single twisted pair. It is rated for +1000meter cables. 1/10 of the speed of 100BaseTX, but 10x the range.

1Gbps may actually be easier than 100mbps from an EMC perspective. 100mbps links are infamous for trashing HAM frequencies. Indeed, when I played around with my RTL-SDR at home, the FM spectrum was littered with harmonic spikes originating from the one and only 100mbps link I had at the time.
