Revision 1050242fa657093d3788c3ffa0bd9b42e4d7d1ab authored by Aaron Ma on 18 June 2020, 06:54:53 UTC, committed by Tony Nguyen on 30 July 2020, 17:04:54 UTC
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.
Fixes: 0c80cdbf3320 ("e1000e: Warn if disabling ULP failed")
