Reading the RSSI from a Kernel Module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 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
