Yes, you can not use both pcieqos and pch_phub at the same time.
Because pcieqos is previous version of pch_phub which is upstreamed.

Saving MAC address into external ROM is generic method, I think.
Though I know the ROM-less system using eg20t-pch, however I think
this system is not common.
So, I think pch_gbe shouldn't have auto-mac address assignment.

BTW, as you know, a use can write MAC address using sysfs file system
like below.
echo aa:bb:cc:dd:ee:ff > pch_mac

thanks,
