Since I'm new to this domain, let me start by thanking you for your patience.

I've noticed that libpcap based  packet injection software (packetspammer and 
reaver) are transmitting packets twice with different radiotap headers between 
the original and the duplicate on my box (ath9k).  In order to troubleshoot, 
I'd like to improve control over the  radiotap headers.   Packetspammer 
includes its own version of the relevant files (e.g ieee80211_radiotap.h) and 
reaver does the least possible.  While the relevant header files are included 
with the kernel, they aren't in the linux-headers package on Gentoo or 
included anywhere under /usr/include.   I do have nl80211.h file that will let 
me query settings, but doesn't understand anything about radiotap.  

What is the proper way to include querying and generating radiotap headers?

Thanks in advance for your help.

Regards,

Mark Gannon
