Subject: [PATCH] [PCI] move ICHx GbE NVM write-protection from e1000e to PCI
	quirk

From: Bruce Allan <bruce.w.allan@...el.com>

The write-protection method being in the driver probe routine is called
late in the boot sequence, and not at all if the driver is never loaded.
By making it a PCI quirk the NVM is protected much earlier whether or not
the driver is loaded.  The write-protection quirk can be disabled with a
new kernel parameter in the unlikely event the NVM needs to be modified.
