Merge branch 'amd-xgbe-next'

Tom Lendacky says: ==================== amd-xgbe: AMD XGBE driver updates 2014-09-03 The following series of patches includes fixes/updates to the driver. - Query the device for the actual speed mode (KR/KX) rather than trying to track it - Update parallel detection logic to support KR mode - Fix new warnings from checkpatch in the amd-xgbe and amd-xgbe-phy driver This patch series is based on net-next. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
