From what I've seen of QMAP it seems like a reasonable design choice to
have a software component (rmnet) dealing with this, separate from the
transport. And I think IPA is the 4th or 5th mechanism for transporting
QMAP packets back and forth to the modem.


Downstream rmnet is copyright 2007-, and I know of interest in bringing
at least one of the other transports upstream.
