    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.
