Re: [Intel-wired-lan] [PATCH] e1000e: disregard NVM checksum on tgp when valid checksum mask is not set

If no update is available, perhaps we can consider ignoring the checksum on TGP systems if one of the following conditions is met:
1. SW compatibility bit is not set (current Jacek's approach)
2. The checksum word at offset 0x3F retains its factory default value of 0xFFFF.

I am already on the latest firmware. I have also tried downgrading to earlier versions and they have the same problem.

Ok, so in this case I think that we should go with option 2.

Jacek - can you please add this check to your patch?

Yes, I'll prepare v2 by the end of this week.
