Subject: [PATCH] Use link_ready_wait instead of up flag check loop

A loop checking the link UP flag was immediately successful
and thus useless. Use a short 3 sec link_ready_wait instead
to give the kernel some time to apply scope local address
and start async tasks like IPv6 dad and avoid some of the
initial send errors reported by dhclient6 (bnc#697929).
