Yes, I understand that, but until the IFF_UP flag is set on the interface, it doesn't really have any effect on the system as a whole. You should be able to undo any default setting that you want before you call ifup on the interface, or am I missing something?
If i understand what you are proposing, in that context you can't undo before you set IFF_UP because the sysfs entries do not exist yet, and undoing later is too late as in the case of auto-configuration for instance the kernel might already have sent a RtSol.
