e1000e: 82566DC fails to get link
Two recent patches to cleanup the reset[1] and initial PHY configuration[2] code paths for ICH/PCH devices inadvertently left out a 10msec delay and device ID check respectively which are necessary for the 82566DC (device id 0x104b) to be configured properly, otherwise it will not get link. [1] commit e98cac447cc1cc418dff1d610a5c79c4f2bdec7f [2] commit 3f0c16e84438d657d29446f85fe375794a93f159 CC: stable@kernel.org Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Tested-by: Jeff Pieper <jeffrey.e.pieper@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
