No idea, the high power consumption and latency of >1000baseT were such that I've never had any interest in anything newer in baseT land.

At home I run 10/100/1000baseT, 10Gbase-SR, 40Gbase-SR4, and am just beginning to prepare for 25Gbase-SR and 100Gbase-SR4 deployments (I have some NICs and optics fielded but no switching yet).

I've worked with 100baseT1 and 1000baseT1 for automotive projects at work and am familiar with the line coding, and have written a protocol decode for 100baseT1 among others, but I don't use them in my own projects.

When I last looked into it, which was admittedly several years ago, 10GbaseT PHYs were unobtainium in the "I want to buy just one, without an NDA" space. Your best option for putting 10Gbase-T on a DIY design is to put a SFP+ cage on there and slap in a baseT SFP+ module that somebody else designed.

Indeed this seems to be the case. I hate this. There's no reason to make hardware inaccessible.
