This is being done to allow the DPP module to work correctly. DPP
currently uses __station_connect_network incorrectly since it
does not (and cannot) change the state after calling. The only
way to connect with a state change is via station_connect_network
which requires a DBus method that triggered the connection; DPP
does not have this due to its potentially long run time.
To support DPP there are a few options:
1. Pass a state into __station_connect_network (this patch)
2. Support a NULL DBus message in station_connect_network. This
would require several NULL checks and adding all that to only
support DPP just didn't feel right.
3. A 3rd connect API in station which wraps
__station_connect_network and changes the state. And again, an
entirely new API for only DPP felt wrong (I guess we did this
for network_autoconnect though...)
Its about 50/50 between call sites that changed state after calling
and those that do not. Changing the state inside
__station_connect_network felt useful enough to cover the cases that
could benefit and the remaining cases could handle it easily enough:
- network_autoconnect(), and the state is changed by station after
calling so it more or less follows the same pattern just routes
through network. This will now pass the CONNECTING_AUTO state
from within network vs station.
- The disconnect/reconnect path. Here the state is changed to
ROAMING prior in order to avoid multiple state changes. Knowing
this the same ROAMING state can be passed which won't trigger a
state change.
- Retrying after a failed BSS. The state changes on the first call
then remains the same for each connection attempt. To support this
the current station->state is passed to avoid a state change.
