I've been thinking about this one for a while, and I think the default
is backwards.

The intent is to allows users to implement network services over layer
2, and not to be a packet intereceptor or snooper.  The current default
of being non-exclusive is more useful to the sniffer than the network
services provider.

Therefore I'd like to change L2_EXCLUSIVE to L2_NONEXCLUSIVE and fix up
the logic as appropriate

        L2_NONEXCLUSIVE, int (bool)
                If false (the default) then a frame is considered
                delivered when it is sent to an l2 socket.  Otherwise
                the frame is also eligible to be sent to other sockets 
                and for layer-3 processing.

Thanks,
Chris.
