Do you have any reason to believe that the driver you are using supports
this?

That would sound like a clear sign of the driver not supporting this..

Only a single P2P group case can use a specific netdev since that same
netdev is used for both P2P management operations and group. In order to
use multiple concurrent groups, the only available option is to use a new
group interface for each group.
