Ben Wei started a thread "Out-of-band NIC management" in openbmc community for NCSI management using netlink, and you may follow up with him for details. > > I haven't decided what to do in my v2 patch: maybe using device tree, maybe moving the logic to uboot, and I'm also evaluating the netlink option. But it shouldn't impact your patch, because you can disable NCSI_OEM_GET_MAC option from your config file. Thanks Tao. I see now that disabling the NCSI_OEM_GET_MAC option will do what I want.
