Getting information from a received packet's header

Thank you for the idea!

Anyway, it won't work for me. I need the card monitoring the packets also to
be able to send.

The protocol I'm trying to implement is the following:
There are two stations connected to the same AP and close to each other. If
there's any traffic between these stations, that would normally go through
the AP, then let's send this traffic directly to the other station.

That's why I need information from all the stations, so the sender can find
out, where it is able to send the packets directly (eg packets received with
high signal ratio).
