It depends on how you're connecting the modem right now. If you have
just one single APN connection, you could still do that WDS bind of a
given mux id to the whole interface specified by the ep-iface-number.

With the new method, you'll be able to instantiate a whole new network
interface as a "link" of the parent network interface, and use the new
interface for a specific mux-id. This new method allows you to have
multiple connections (e.g. to different APNs) multiplexed over a
single network interface.

This will all be supported by ModemManager as well.
