/* Notes:
 * 1. Put all task priority and stack size definition in this file
 * 2. If the task priority is less than 10, use ESP_TASK_PRIO_MIN + X style,
 *    otherwise use ESP_TASK_PRIO_MAX - X style
 * 3. If this is a daemon task, the macro prefix is ESP_TASKD_, otherwise
 *    it's ESP_TASK_
 * 4. If the configMAX_PRIORITIES is modified, please make all priority are
 *    greater than 0
 * 5. Make sure esp_task.h is consistent between wifi lib and idf
 * 6. If changing system task priorities, please check the values documented in /api-guides/performance/speed.rst
 * are up to date
