esp_wifi_internal_tx_by_ref() function
transmit the buffer by reference via wifi driver This API firstly increases the reference counter of the input buffer and then forwards the buffer to WiFi driver. The WiFi driver will free the buffer after processing it. Use esp_wifi_internal_tx() if the uplayer buffer doesn't supports reference counter.
