Re: [time-nuts] IEEE 1588 PTP support on raspberry pi 4 compute module

Essentially all home switches and routers have no PTP support. Most
professional equipment doesn't. We only see it in dedicated
environments, and not all of those that should have it does, with margin.
This is not to say that PTP is not sensitive to asymmetries, it is, and
it is clearly stated upfront in the IEEE 1588 standard.
