4523 * This function is used to request time for an operation that requires
4524 * exclusive radio control. Once the radio is available, the registered callback
4525 * function will be called. radio_work_done() must be called once the exclusive
4526 * radio operation has been completed, so that the radio is freed for other
4527 * operations. The special case of deinit=1 is used to free the context data
4528 * during interface removal. That does not allow the callback function to start
4529 * the radio operation, i.e., it must free any resources allocated for the radio
4532 * The @freq parameter can be used to indicate a single channel on which the
4533 * offchannel operation will occur. This may allow multiple radio work
4534 * operations to be performed in parallel if they apply for the same channel.
4535 * Setting this to 0 indicates that the work item may use multiple channels or
4536 * requires exclusive control of the radio.
