After 'commit e086ba2fccda4 ("e1000e: disable s0ix entry and exit flows for ME systems")', ThinkPad P14s always failed to disable ULP by ME. 'commit 0c80cdbf3320 ("e1000e: Warn if disabling ULP failed")' break out of init phy: error log: [ 42.364753] e1000e 0000:00:1f.6 enp0s31f6: Failed to disable ULP [ 42.524626] e1000e 0000:00:1f.6 enp0s31f6: PHY Wakeup cause - Unicast Packet [ 42.822476] e1000e 0000:00:1f.6 enp0s31f6: Hardware Error When disable s0ix, E1000_FWSM_ULP_CFG_DONE will never be 1. If continue to init phy like before, it can work as before. iperf test result good too.
