Thank you for deciding  :-)

Now one more question.  So we will have two callbacks from NetDevice to
Node.  How do you want to handle Node::AddProtocolHandler and promiscuous
mode:

   1- Node::AddProtocolHandler (callback1) and
Node::AddPromiscuousProtocolHandler (callback2), each with different
callback signatures;

   2- Single Node::AddProtocolHandler (promiscuousMode=false, callback),
with changes in callback signature;

Thanks in advance.
