I'm not sure I understand you. Can you please elaborate more? Not sure
how this is related to iproute2.

Anyway, the kernel behaviour wrt use_tempaddr settings remains unchanged
with the addition of IFA_F_MANAGETEMPADDR. It only allows to create temp
addresses for other addresses than the ones created by kernel (by RA).
