/**
  * @brief  Init WiFi
  *         Alloc resource for WiFi driver, such as WiFi control structure, RX/TX buffer,
  *         WiFi NVS structure etc, this WiFi also start WiFi task
  *
  * @attention 1. This API must be called before all other WiFi API can be called
  * @attention 2. Always use WIFI_INIT_CONFIG_DEFAULT macro to init the config to default values, this can
  *               guarantee all the fields got correct value when more fields are added into wifi_init_config_t
  *               in future release. If you want to set your owner initial values, overwrite the default values
  *               which are set by WIFI_INIT_CONFIG_DEFAULT, please be notified that the field 'magic' of 
  *               wifi_init_config_t should always be WIFI_INIT_CONFIG_MAGIC!
  *
  * @param  config pointer to WiFi init configuration structure; can point to a temporary variable.
  *
  * @return
  *    - ESP_OK: succeed
  *    - ESP_ERR_NO_MEM: out of memory
  *    - others: refer to error code esp_err.h
