Tao, in your new patch will it be possible to disable the setting of
the BMC MAC? I would like to be able to send NCSI_OEM_GET_MAC
perhaps with netlink (TBD) to get the system address without it
affecting the BMC address.
I was about to send patches to add support for the Intel adapters
when I saw this thread.
Thanks,

Hi Terry,
Sounds like you are planning to configure BMC MAC address from user
space via netlink? Ben Wei <ben...@fb.com> 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.
Best,
Terry
Hi Tao,
After a second look, it appears that the OEM handlers for Broadcom and
Melanox in ncsi-rsp.c will set the MAC regardless of the origin of the
request. Even with NCSI_OEM_GET_MAC disabled, sending an OEM command
with netlink would result in setting the BMC MAC.
Thanks,
Terry
