I still wonder how source address selection should work for
IFA_F_MANAGETEMPADDR if use_tempaddr != 2 mode is not available for
those addresses.

Up until now applications can bind to those addresses and traffic can be
received for them, but there is now way how a user can specify to favor them
in case of use_tempaddr == 0.

Greetings,

  Hannes
