wps_registrar_config::set_sel_reg_cb field

set_sel_reg_cb - Callback for reporting selected registrar changes @ctx: Higher layer context data (cb_ctx) @sel_reg: Whether the Registrar is selected @dev_passwd_id: Device Password ID to indicate with method or specific password the Registrar intends to use @sel_reg_config_methods: Bit field of active config methods This callback is called whenever the Selected Registrar state changes (e.g., a new PIN becomes available or PBC is invoked). This callback is only used by External Registrar implementation; set_ie_cb() is used by AP implementation in similar caes, but it provides the full WPS IE data instead of just the minimal Registrar state information.
