如题，小弟最近在做一个Project，需要在Wi-Fi帧内插入自己定义的一段内容，请问应该如何做到呢？是不是要通过mac80211去重新编写无线网卡的驱动呢？之前没有太多驱动方面的经验，请大神给个思路吧~谢谢啦

I am developing a software now and I hope to modify Wi-Fi frame.
For example, beacon frame contains Frame Control, Duration, DA, SA, SSID, Sequence Control, Frame Body and FCS. I want to add a new field and write something in it. How can I realize that? Should I rewrite the drive program for AP and compile it ? Does Open-WRT provide some APIs to do that?
