    ethtool: (uapi) Add ETHTOOL_PHY_DOWNSHIFT to PHY tunables

    For operation in cabling environments that are incompatible with
    1000BASE-T, PHY device may provide an automatic link speed downshift
    operation. When enabled, the device automatically changes its 1000BASE-T
    auto-negotiation to the next slower speed after a configured number of
    failed attempts at 1000BASE-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.
