ethtool: provide UAPI for PHY Signal Quality Index (SQI)
Signal Quality Index is a mandatory value required by "OPEN Alliance
SIG" for the 100Base-T1 PHYs [1]. This indicator can be used for cable
integrity diagnostic and investigating other noise sources and
implement by at least two vendors: NXP[2] and TI[3].
