Hi,
I am using Intel I210 ethernet controller P/n:WGI210IT.
The IC is programmed using eeupdate tool with iNVM image and is working perfectly at positive temperature(above 0 degC) checked up to +55C
But the IC is not working(not even getting detected as a pci device in linux with lspci; also checked with lanconf tool, it is not showing the adapter) at -ve temperatures.
The marking on the IC shows that it is an industrial grade part. All other components used in the design are rated for -40 to 85C.
Please help me in resolving this issue
