+ * @brief Send user-define 802.11 packets.
+ *
+ * @attention 1. Packet has to be the whole 802.11 packet, does not include the FCS.
+ * The length of the packet has to be longer than the minimum length
+ * of the header of 802.11 packet which is 24 bytes, and less than 1400 bytes.
+ * @attention 2. Duration area is invalid for user, it will be filled in SDK.
+ * @attention 3. The rate of sending packet is same as the management packet which
+ * is the same as the system rate of sending packets.
+ * @attention 4. Only after the previous packet was sent, entered the sent callback,
+ * the next packet is allowed to send. Otherwise, wifi_send_pkt_freedom
+ * will return fail.
+ *
+ * @param uint8 *buf : pointer of packet
+ * @param uint16 len : packet length
+ * @param bool sys_seq : follow the system's 802.11 packets sequence number or not,
+ * if it is true, the sequence number will be increased 1 every
+ * time a packet sent.
+ *
+ * @return ESP_OK, succeed;
+ * @return ESP_FAIL, fail.
