currently, we worked on a Qualcomm CDMA chip, and it worked on a Relay
mode, just relay the air PPP packet to host, and in Ofono we should
support PFC to satisfy the spec (Sprint Spec.), But Ofono does not
support PFC, so comes this question.
From my personal point, Ofono should support PFC.
as you might have clearly figured from Denis and my responses, our PPP
code was designed to talk to a modem, not a network.
We don't want to implement a full blown PPP stack with all nasty
features. If this is needed for CDMA, because they push the PPP frames
over the air, then actually getting the kernel PPP frame processing
hooked up to our LCP and IPIP userspace code is the right thing to do
here.
At the moment we are not really putting additional energy into PPP since
it is a dying protocol in the GSM world. The networks never required it
and the modem hardware/firmware moves over to highspeed direct IP
interfaces.

Marcel
