[PATCH 5.15 158/262] e1000e: Correct NVM checksum verification flow

[Greg Kroah-Hartman]

From: Sasha Neftin <sasha.neftin@xxxxxxxxx>

commit ffd24fa2fcc76ecb2e61e7a4ef8588177bcb42a6 upstream.

Update MAC type check e1000_pch_tgp because for e1000_pch_cnp,
NVM checksum update is still possible.
Emit a more detailed warning message.

Bugzilla: https://bugzilla.opensuse.org/show_bug.cgi?id=1191663
Fixes: 4051f68318ca ("e1000e: Do not take care about recovery NVM checksum")
