Doesn't my original suggestion still stand... regardless of how this particular problem is fixed? That is: if the sending MAC address is _our_ MAC address, then the address is not duplicate. It seems a simple change (unless the function that processes the packet would have difficulty determining the MAC address) and it seems to be infallible logic. In fact, if we receive a packet from our own MAC address, shouldn't we drop and log it?
