Topic: How to modify Wi-Fi frame ?

The content of this topic has been archived on 31 Mar 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

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?

This is not OpenWrt specific. Read into mac80211, nl80211, hostapd.
