e1000e : The NVM Checksum Is Not Valid

[   19.934486] e1000e 0000:06:00.0: (unregistered net_device): The NVM Checksum Is Not Valid
[   20.042663] e1000e 0000:06:00.0: PCI INT A disabled
[   20.101079] e1000e: probe of 0000:06:00.0 failed with error -5



I ran into this issue and spent few hours looking for a solution.
the solution that I found ( the one that actually worked ) was through Intel's NIC tools.


1. download  Preboot.tar.gz
2. decpompress the file tar xvfz Preboot.tar.gz
3. cd APPS/BootUtil/
use appropriate bootutil binary "bootutil32" or "bootutil64e"
# cd Linux_x64/
# chmod 755  bootutil64e
# rmmod e1000e 
# ./bootutil64e -WOLD -ALL
# ./bootutil64e -WOLE -ALL
# modprobe e1000e

hope this might save some of your time looking for a working solution.
