There is support for setting SSID when starting an autonomous GO for a
non-persistent group indeed.
Before calling wpas_p2p_group_add(), set p2p->ssid and p2p->ssid_set,
then p2p_go_param() would skip the SSID generation step and use
p2p->ssid instead.
What you said is for saved network (e.g. persistent group), and we
need to start an autonomous GO for a non-persistent group with
pre-defined ssid and passphrase in the fly.
Since p2p_go_param() allows a pre-defined SSID, why not a pre-defined
passphrase.
We are implementing a function for starting an autonomous GO for
non-persistent group with pre-defined ssid and passphrase.
This would need this functionality.
Thank you for your time and consideration.
Best regards,
Jimmy
