* igb: add support for 1512 PHYTodd Fujinaka2015-08-181-3/+17
| | | | | | | | | This patch adds support for Marvell PHY 1512 (required for I354). Submitted by: Maciej Szwed <maciej.szwed@intel.com> Signed-off-by: Todd Fujinaka <todd.fujinaka@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
* igb: Fix i354 88E1112 PHY on RCC boards using AutoMediaDetectTodd Fujinaka2015-07-171-5/+13
| | | | | | | | | | | | e1000_check_for_link_media_swap() checks PHY page 0 for copper and PHY page 1 for "other" (fiber) link. The switch back from page 1 to page 0 happened too soon, before e1000_check_for_link_82575() is executed, and link on fiber (other) was never detected. Check for link while still on the proper PHY page.

| | | | | | | | | | | | | | | | | | | | | | | | | | On some devices, the internal PLL circuit occasionally provides the wrong clock frequency after power up. The probability of failure is less than one failure per 1000 power cycles. When the failure occurs, the internal clock frequency is around 1/20 of the correct frequency.

* igb: Add new feature Media Auto Sense for 82580 devices onlyCarolyn Wyborny2013-12-101-0/+13
| | | | | | | | | | | | | | This patch adds support for the hardware feature Media Auto Sense. This feature requires a custom EEPROM image provided by our customer support team. The feature allows hardware designed with dual PHY's, fiber and copper to be used with either media without additional EEPROM changes. Fiber is preferred and driver will swap and configure for fiber media if sensed by the device at any time. Device will swap back to copper if it is the only media detected.
