ConnMan has two 'online' states. READY and ONLINE. The READY state means
the interface has been successfully configured (e.g. DHCP was
successful). Then ConnMan tries to figure out if a remote IP is
reachable (so there is an uplink to the internet) the will go to the
ONLINE state.

There a bunch of knobs which control the ONLINE check.

We had some changes in the ordering and updating logic for the service
list. It's possible there is something wrong. Could you post a log
output from ConnMan? Maybe I can spot what's wrong.

Does ConnMan assign a IPv4 link local address (169.254.0.0/16)?

Not sure if this is related to the above ONLINE check.
