Hi,

I have noticed that the Rx trace source of WifiNetDevice is called
whenever _any_ frame is received, including overheard ones -- i.e.
directed to some other host.
Is this "by design"? If so, I feel:
* it should be stated clearly in the documentation -- to me, "Received
payload from the MAC layer." suggests that the MAC layer has also
checked that the frame is really for the host;
* users of the trace should be given a fast way to detect whether the
frame is being overheard or not - e.g. passing the destination address
along with the source one.

Francesco
