E610 NICs unlike the previous devices utilising ixgbe driver
are notified in the case of overheat by the FW ACI event.

In event of overheat when treshhold is exceeded, FW suspends all
traffic and sends overtemp event to the driver. Then driver
loggs appropriate message and closes the adapter instance.
The card remains in that state until the platform is rebooted.
