Commit Message

Jedrzej Jagielski Feb. 13, 2025, 7:44 a.m. UTC 
E610 NICs unlike the previous devices utilizing 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 closes 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.
