Date: Wed, 22 Sep 2010 20:15:33 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org, gospo@...hat.com, bphilips@...ell.com, Bruce Allan <bruce.w.allan@...el.com>, Jeff Kirsher <jeffrey.t.kirsher@...el.com> 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.
