Subject: [net-2.6 PATCH 2/6] e1000e: 82579 SMBus address and LEDs incorrect
	after device reset

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

Since the hardware is prevented from performing automatic PHY configuration
(the driver does it instead), the OEM_WRITE_ENABLE bit in the EXTCNF_CTRL
register will not get cleared preventing the SMBus address and the LED
configuration to be written to the PHY registers.  On 82579, do not check
the OEM_WRITE_ENABLE bit.
