At this point, I think it is best to just completely pull out all concept of "default addresses" in the IPMI driver. The defaults were disabled by default in 3.16, this is as good an impetus as any to just get rid of them.
If you want, you can do a patch, or I can pull them out if you would prefer that.
Thanks,
