Date: Mon, 15 Dec 2014 16:39:13 +0800 From: Zhu Yanjun <zyjzyj2000@...il.com> To: netdev@...r.kernel.org, w@....eu, zyjzyj2000@...il.com Cc: Zhu Yanjun <Yanjun.Zhu@...driver.com>, Bruce Allan <bruce.w.allan@...el.com>, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [PATCH 4/5] e1000e: update workaround for 82579 intermittently disabled during S0->Sx 2.6.x kernels require a similar logic change as commit c6f8b74f [e1000e: update workaround for 82579 intermittently disabled during S0->Sx] introduces for newer kernels. The workaround which toggles the LANPHYPC (LAN PHY Power Control) value bit to force the MAC-Phy interconnect into PCIe mode from SMBus mode during driver load and resume should always be done except if PHY resets are blocked by the Manageability Engine (ME). Previously, the toggle was done only if PHY resets are blocked and the ME was disabled. The rest of the patch is just indentation changes as a consequence of the updated workaround.
