It actually fixes issues on the non-ME i219V as well. Can this one be queued up and we can keep discussing the rest? > diff --git a/drivers/net/ethernet/intel/e1000e/netdev.c b/drivers/net/ethernet/intel/e1000e/netdev.c > index b30f00891c03..128ab6898070 100644 > --- a/drivers/net/ethernet/intel/e1000e/netdev.c > +++ b/drivers/net/ethernet/intel/e1000e/netdev.c > @@ -6475,13 +6475,13 @@ static void e1000e_s0ix_entry_flow(struct e1000_adapter *adapter) > > /* Ungate PGCB clock */ > mac_data = er32(FEXTNVM9); > - mac_data |= BIT(28); > + mac_data &= ~BIT(28); > ew32(FEXTNVM9, mac_data); > > /* Enable K1 off to enable mPHY Power Gating */ > mac_data = er32(FEXTNVM6); > mac_data |= BIT(31); > - ew32(FEXTNVM12, mac_data); > + ew32(FEXTNVM6, mac_data); > > /* Enable mPHY power gating for any link and speed */ > mac_data = er32(FEXTNVM8); > @@ -6525,11 +6525,11 @@ static void e1000e_s0ix_exit_flow(struct e1000_adapter *adapter) > /* Disable K1 off */ > mac_data = er32(FEXTNVM6); > mac_data &= ~BIT(31); > - ew32(FEXTNVM12, mac_data); > + ew32(FEXTNVM6, mac_data); > > /* Disable Ungate PGCB clock */ > mac_data = er32(FEXTNVM9); > - mac_data &= ~BIT(28); > + mac_data |= BIT(28); > ew32(FEXTNVM9, mac_data); > > /* Cancel not waking from dynamic -- *Mario Limonciello* *Dell*| CPG Software Engineering *office*+1 512 723 0582

Not sure Dave will notice this discussion, best if you repost this patch separately. If it's a fix that should be backported to stable make sure you add a Fixes tag.
