For example, if the channel is 3, the scan order will be 3, 1, 2, 4,..., N. If you do not know which channel the target AP is running on, set it to 0.

- Avoid using more than two precedences supported by different AMPDUs, e.g., when socket A uses precedence 0, socket B uses precedence 1, and socket C uses precedence 2. This can be a bad design because it may need much more memory. To be specific, the Wi-Fi driver may generate a Block Ack session for each precedence and it needs more memory if the Block Ack session is set up.
