Is pipe/pep concept in ISI modem, specific to a modem inside N900? Or is it generic to
any Nokia modem?

It should be available in any Nokia modem that exposes the USB CDC Phonet
vendor-specific interface. If I recall correctly, it worked with my Nokia
N95.

Today's Phonet stack in 2.6.24, gprs interface looks like virtual interface (similar
to TUN) where no connection with real hardware is possible.
I can't understand how peps (one on modem and other on linux phonet stack) are
connected, so that IP packets coming from nokia modem can be forwarded to IP stack
directly instead of routing from user space using sequence socket.
Is it possible with today's phonet stack? Is there a need of third entity like
controller to do this?
Thanks,
Hvr

Phonet was released in Linux kernel 2.6.27 if I recall correctly.

to IP stack directly instead of routing from user space using sequence

The virtual GPRS network interface runs on top of the Phonet packet socket,
much like a virtual PPP network interfaces run on top of a TTY port.
The packet socket itself is the Linux-side endpoint of the Phonet pipe between
the modem and the Linux CPU.

That's done with the pep_gprs.c network device driver. However, GPRS signaling
needs to be done in userspace. This is implemented in oFono already.
