I think we generally have full 'connector' and abbreviated
'conn_state'. A bit inconsistent in itself but IMO still better
to stick to common naming conventions so the poor brain has an
easier job when reading code. We could perhaps do a
s/connector/conn/ over the whole codebase to make things a bit
shorter in a bunch of places.
