Sorry, I was recalling this from memory without looking at the code.
link-locals are always marked "permanent"
global addresses added by hand are marked "permanent"
global addresses added by auto-configuration are marked "dynamic"
(/sbin/ip prints this if IFA_F_PERMANENT is not set)
That way you can tell if they were added by the kernel or the user.
