It would be insane for a switch to have EEE enabled without a way to
turn it off, so you likely have never seen it turned on.
I can enable autonegotiation for EEE it on some of my switches, nothing
but trouble.
If your backbone is GigE then it is likely way better than you think.
Turn on PTP and your hosts will time link closer than you have ever
seen, if it works at all. Hardware timestamping of the ethernet packets
works well, when it works at all.
PTP shows that the main problem with high accuracty NTP is the network
stack and the OS, not the network itself.
