This might be off topic, but AFAIR there are PPP type PDP contexts where not raw IP, but actual PPP frames are transmitted over GPRS inside SNDCP/LLC. Not sure if any operators use that, but its perfectly valid.
Yes, I think this was introduced in Release 7. However, it would require the use of "PPP" pdp type in CGDCONT, not "IP". Also, for EPS contexts I don't believe that "PPP" type is possible (nor wanted, as you'd fry your CPU keeping up with the high-bandwidth connection). Probably a legacy feature that might still be used in very narrow circumstances. I've certainly never seen it used in practice.
In this case PPP doesn't terminate in the modem, so "hardware" support should be irrelevant.
True. But I'm probably missing your point. PPP packet compression is still an optional protocol feature, so it should not preclude interoperability.
