Hi Jouni,

               As per my understanding currently, same PSK is being shared
for all the clients of the same GO. Your suggestion is to have one PSK per
client. But my requirement is  to disconnect a particular client form GO.
Can I achieve this from following steps:
1. Adding a new command for client disconnect in interface.
2. this disconnect command will send a disassociation frame to that client.
3. Remove client from peer list and clean up all the client resources from
supplicant of GO.
