e1000e ULP issue

Using Maciej Pijanowski's  m920q review, I was able to get coreboot 
booting on a Lenovo m720q.

However, I get a strange error in Linux under coreboot.

  e1000e 0000:00:1f.6 0000:00:1f.6 (uninitialized): Failed to disable ULP

There is also a potentially related ACPI complaint:
ACPI Error: AE_NOT_FOUND, While resolving a named reference package 
element - \_SB_.PCI0.IGBE (20230331/dspkginit-438)

The gbe Ethernet controller is built in:

00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (7) 
I219-V (rev 10)

Several other existing boards seem also have I219 devices  but I 
couldn’t find any special handling for this.    I'm not familiar with 
ULP, but it seems the ME could turned it on.   I still have the original 
ME and GBE sections in the flash.

Has anyone seen this issue before?  Or should I try to add coreboot code 
to disable ULP in the Ethernet PHY? (seems a bit strange).

Thanks!
