This patches are extending ethtool netlink interface to export Signal Quality Index (SQI). SQI provided by 100Base-T1 PHYs and can be used for cable diagnostic. Compared to a typical cable tests, this value can be only used after link is established.
changes v3: - rename __ethtool_get_sqi* to linkstate_get_sqi*. And move this functions to the net/ethtool/linkstate.c - protect linkstate_get_sqi* with locking changes v2: - use u32 instead of u8 for SQI - add SQI_MAX field and callbacks - some style fixes in the rst. - do not convert index to shifted index.
