5427 * function will be called. radio_work_done() must be called once the exclusive
5428 * radio operation has been completed, so that the radio is freed for other
5429 * operations. The special case of deinit=1 is used to free the context data
5430 * during interface removal. That does not allow the callback function to start
5431 * the radio operation, i.e., it must free any resources allocated for the radio
5434 * The @freq parameter can be used to indicate a single channel on which the
5435 * offchannel operation will occur. This may allow multiple radio work
5436 * operations to be performed in parallel if they apply for the same channel.
5437 * Setting this to 0 indicates that the work item may use multiple channels or
