commit f5a4732f85613b3fb43f8bc33a017e3db3b3605a Author: Raju Lakkaraju <raju.lakkar...@microsemi.com> Date: Wed Nov 9 16:33:09 2016 +0530 ethtool: (uapi) Add ETHTOOL_PHY_GTUNABLE and ETHTOOL_PHY_STUNABLE For operation in cabling environments that are incompatible with 1000BAST-T, PHY device may provide an automatic link speed downshift operation. When enabled, the device automatically changes its 1000BAST-T auto-negotiation to the next slower speed after a configured number of failed attempts at 1000BAST-T. This feature is useful in setting up in networks using older cable installations that include only pairs A and B, and not pairs C and D.
