step. If the WPS provisioning step has been completed, the group is not
terminated.
p2p_remove_client <peer's P2P Device Address|iface=<interface address>>
This command can be used to remove the specified client from all groups
(operating and persistent) from the local GO. Note that the peer device
can rejoin the group if it is in possession of a valid key. See p2p_set
per_sta_psk command below for more details on how the peer can be
removed securely.

(DIRECT-<two random characters>). For example, postfix of "-testing"
could result in the SSID becoming DIRECT-ab-testing.
p2p_set per_sta_psk <0/1>
Disabled(default)/enables use of per-client PSK in the P2P groups. This
can be used to request GO to assign a unique PSK for each client during
WPS provisioning. When enabled, this allow clients to be removed from
the group securily with p2p_remove_client command since that client's
PSK is removed at the same time to prevent it from connecting back using
the old PSK. When per-client PSK is not used, the client can still be
disconnected, but it will be able to re-join the group since the PSK it
learned previously is still valid. It should be noted that the default
passphrase on the GO that is normally used to allow legacy stations to
connect through manual configuration does not change here, so if that is
shared, devices with knowledge of that passphrase can still connect.
