    phylink: add helper for configuring 2500BaseX modes · 624c0f02
    Russell King authored
    Add a helper for MAC drivers to use in their validate callback to deal
    with 2500BaseX vs 1000BaseX modes, where the hardware supports both
    but it is not possible to automatically select between them.
    This helper defaults to 1000BaseX, as that is the 802.3 standard, and
    will allow users to select 2500BaseX either by forcing the speed if
    AN is disabled, or by changing the advertising mask if AN is enabled.
    Disabling AN is not recommended as it is only the speed that we're
    interested in controlling, not the duplex or pause mode parameters.
