Subject: Using Wireless Extensions in a Kernel Module

Hi,

I am trying to write a Kernel Module with an implementation of a new  
TCP-Algorithm. Since I need to know the RSSI-Value (Received Signal  
Strength indication) of the sent package, I extended the Pluggable  
Congestion Control Mechanism by a new function which is called right  
after the package is send. At that point, I need to read the RSSI-Value.

I'm now trying to somehow access that value, but I can't figure out  
how. I've come as far, that I found out about the Wirelless  
Extensions, which seem to be very promising. In the header file the  
author states, that this mechanism can be used by both user-space apps  
and kernel modules. Unfortunately nobody seems to ever have used it in  
kernel space, since I can't find any documentations about it.

I would be very glad, if somebody could give me link to a page  
containing informations about this topic, or even just a hint that  
could help me.

Thank you

Tim Schneider
