Thanks for the comments from Miss Wang.  Actually，I think IWF means it
can perform both layer2 and IP function. Therefore, IWF can be
performed in a layer 2 node, such as an ATM switch, which works like
the IPv4oA IWF in ATM switch usually.  And it can also be performed
in a layer 3 node, BRAS as an example. In this draft, we just defined
IWF is in a layer 2 node.
