So basically, the purpose of the rmnet driver is to handle QMAP
protocol connections, and right now that's what the modem provides.

Do you have any idea why this particular design was picked?

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.
