net: phy: add an option to disable EEE advertisement
This patch adds an option to disable EEE advertisement in the generic PHY by providing a mask of prohibited modes corresponding to the value found in the MDIO_AN_EEE_ADV register. On some platforms, PHY Low power idle seems to be causing issues, even breaking the link some cases. The patch provides a convenient way for these platforms to disable EEE advertisement and work around the issue.
