At the moment no, there is no way to configure this.

So does the network actually support multiple inner methods? or is this 
just more of a "debugging" feature to determine which (single) method it 
supports. I'd be interested in the motivation for a feature like this. 
Is it:

   - There are _real_ networks that exist which support multiple EAP 
methods, or...

   - Your network administrators are not providing their clients with 
enough information.

I do know its possible to configure/allow multiple EAP methods with 
hostapd at least, so it is _possible_ that networks like this exist. I'm 
more just curious if its done ever in practice, and if so I guess that's 
something IWD might want to support.

Also, you should be able to determine at least if its PSK or enterprise 
based on the AKM in the beacon. And IWD will also print this in the 
debug logs when it scans.

Thanks,

James
