Subject: 3.10: Intel HWMON/NIC temperature sensor question

Hi,

I saw this in the device drive section and was curious which Intel-based
NICs contain temperature sensors?

Intel(R) 10GbE PCI Express adapters HWMON support
Intel(R) PCI-Express Gigabit adapters HWMON support

I checked the boards below and none appear to expose a hwmon interface:
08:00.0 Ethernet controller: Intel Corporation 82580 Gigabit Network
Connection (rev 01)
08:00.1 Ethernet controller: Intel Corporation 82580 Gigabit Network
Connection (rev 01)
08:00.2 Ethernet controller: Intel Corporation 82580 Gigabit Network
Connection (rev 01)
08:00.3 Ethernet controller: Intel Corporation 82580 Gigabit Network
Connection (rev 01)
09:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection
0a:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection
01:00.0 Ethernet controller: Intel Corporation 82598EB 10-Gigabit AT2 Server
Adapter (rev 01)
