The SI unit of voltage is V not v, so milli-volts is mV not mv. Surely,
at the very least, we should be using the SI designation in user
visible strings?

It may also be worth providing a brief description of 10BASE-T1L in the
cover letter so (e.g.) one doesn't have to look up the fact that the
voltage level is negotiated via bit 13 of the base page. I've found
that by searching google and finding dp83td510e.pdf

Thanks.
