This patch series addresses a regression in Energy Efficient Ethernet (EEE) handling for KSZ switches with integrated PHYs, introduced in kernel v6.9 by commit fe0d4fd9285e ("net: phy: Keep track of EEE configuration").
The first patch updates the DSA driver to allow phylink to properly manage PHY EEE configuration. Since integrated PHYs handle LPI internally and ports without integrated PHYs do not document MAC-level LPI support, dummy MAC LPI callbacks are provided.
The second patch removes outdated EEE workarounds from the micrel PHY driver, as they are no longer needed with correct phylink handling.
This series addresses the regression for mainline and kernels starting from v6.14. It is not easily possible to fully fix older kernels due to missing infrastructure changes.
Tested on KSZ9893 hardware.
