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

Fixes: 4051f68318ca9 ("e1000e: Do not take care about recovery NVM
checksum")

I think that while the commit cited above relates to this problem, this bug actually dates back to the patch I'm citing immediately below. And I think we should cite that commit here. IOW, I'm suggesting:

Fixes: fb776f5d57ee ("e1000e: Add support for Tiger Lake")

I had my doubts when choosing a commit for the "Fixes" tag, but since
my setup would most likely work up until 4051f68318ca9, I selected it
specifically.

On my laptop NVM write attempt does (temporarily) fix a checksum
and makes driver loading possible. Only after 4051f68318ca9, which
disabled this code path (because it broke someone else's setup), I'd
be unable to use my network adapter anymore.
