Ubiquitous, eh? Definitely not in consumer space. The RTL8125 that came on my PC doesn't support it. I added an Intel I210 which does support it, after trying an Intel I225 which claims to support it but has a broken implementation.

I'm obviously not familiar with desktop chipsets, but "the RTL8125BG/RTL8125BGS supports IEEE 1588, IEEE 1588-2008, and IEEE 802.1AS, also known as Precision Time Protocol (PTP)" [1] -- don't know if the -BG suffix is a substantially different part.

Mine says it has no hardware clock and consequently no timestamping.

Maybe no driver support in mainline kernel.

Why do you need microsecond precision on a home PC?

I don't, but I did need the hardware timestamping feature to demonstrate certain facts about the linux networking stack.
