I agree that in case of use_tempaddr, the kernel could behave better and
configure the private address even if the option is turned on after the
interface got its address.

But there are options where setting them prior to bringing the interface up may
be very important, e.g. disable_ipv6. The user will rightfully expect that if
this option is set, the interface will not start sending out router
solicitations when brought up. Yet, if we call the sysctl after bringing the
interface up a few solicitations will have been sent out before IPv6 is
disabled on the interface.

So this possible race condition should be taken into account when designing how
this will work.
