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've
already asked this question on the netdev mailing list. They told me,
that there is a new system with a netlink based cfg80211/nl80211
interface in development right now , which is supposed to replace the
wireless extensions in the future. They also told me, that this would
probably be the correct mailing list for this kind of question.
I don't mean to make this a flame so please do not take it that way.
How exactly do you expect to get the RECEIVED Signal Strength indication
for a packet which you are SENDING? If you send it, you don't receive it...
Just my 0.02

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
