Is "online wakeup" a wake up from suspend?
If so: is the Ethernet controller listed with the "wakeup-source" flag
in .dts{,i}?
I'm wondering if the pmdomain and/or power (wakeup) frameworks in
Linux have other ways of managing this case (e.g. only keeping the
power domain active if needed).
Best regards,
