This sounds fine..

.. but this does not do that correctly. network_id is the id of the
network block and it could at least in theory be 0 for the persistent
group parameters and it can certainly be non-zero for a non-persistent
group (if there are other network blocks in the configuration).

network_id is actually unused in the current
wpas_dbus_signal_p2p_group_started(). I think it should actually be
removed since it does not seem to be a very meaningful parameter or at
least not clearly defined (which network? the current ssid block for the
group or the persistent group storage?). The same seems to apply to the
ssid parameter..

In any case, for this new "persistent" parameter, the caller would need
to provide a new function parameter to get this information reliably
into the signal.
