net: phy: micrel: correct KSZ9131RNX EEE capabilities and advertisement
The KSZ9131RNX incorrectly shows EEE capabilities in its registers.
Although the "EEE control and capability 1" (Register 3.20) is set to 0,
indicating no EEE support, the "EEE advertisement 1" (Register 7.60) is
set to 0x6, advertising EEE support for 1000BaseT/Full and
100BaseT/Full.
This inconsistency causes PHYlib to assume there is no EEE support,
preventing control over EEE advertisement, which is enabled by default.
This patch resolves the issue by utilizing the ksz9477_get_features()
function to correctly set the EEE capabilities for the KSZ9131RNX. This
adjustment allows proper control over EEE advertisement and ensures
accurate representation of the device's capabilities.
