I was testing the failover in this setup: CLOCK_REALTIME -> phc2sys -a -r -r -> bond(I210, I350) -> ptp4l -> LAN -> ptp4l -> bond(I350, 82579LM) -> phc2sys -a -r -> CLOCK_REALTIME I suspect the default fault reset interval (16 seconds) might be a bit too long for people interested in this failover, but it is configurable. > 1.
