[ Upstream commit affead2d904e8f82c0b89e23b3835242eb8c3e1a ]
E610 NICs unlike the previous devices utilising ixgbe driver are notified in the case of overheating by the FW ACI event.
In event of overheat when threshold is exceeded, FW suspends all traffic and sends overtemp event to the driver. Then driver logs appropriate message and disables the adapter instance. The card remains in that state until the platform is rebooted.
This approach is a solution to the fact current version of the E610 FW doesn't support reading thermal sensor data by the SW. So give to user at least any info that overtemp event has occurred, without interface disappearing from the OS without any note.
