Hi all,
My Intel E810XXV 25G nic does not re-establish a connection once resuming from suspend (sleep).

One resumed from sleep, I can physically see on the nic that the link and activity lights are blinking. On the switch management side I can also see the link to client is established. So it seems like a software/driver issue to me.
A system reboot re-establishes the link.
