Comment 1 for bug 1486154

Let's fix this by not generating the IFD configuration from DM.

Since DM doesn't have knowledge of PICs/MICs and SW versions,
it will be best to leave the IFD configuration to the user. There
may different devices with slightly different capabilities in
different versions of code. Ideally, we want the user to be able
to use different IFLs on the same IFD for L2 or L3 e.g. unit 0 may
have family bridge while unit 1 has family inet and/or inet6.
