commit 67168af82f30bacbd734a4472670cba6b3d6fd36
Author: Raju Lakkaraju <raju.lakkar...@microsemi.com>

ethtool: (uapi) Add ETHTOOL_PHY_DOWNSHIFT to PHY tunables
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.
