This feature is not supported for E610 which has no support for reading temperature hw->mac.ops.get_thermal_sensor_data() callback used in ixgbe_hwmon_show_temp has no implementation for E610, as there is no such support from the FW side > >Or is the E610 not really an ixgbe, it has a different architecture, ixgbe is used by several adapters, each is slightly different in this case monitoring stuff is pushed into FW >more stuff pushed into firmware, less visibility from the kernel, no >temperature monitoring, just a NIC on fire indication? yeah, right Jedrek
