This should be doable for phonet (and Caif),
Not really no. The API to create a Phonet gprs interface is tightly coupled with the underlying pipe. There are no easy ways to patch the driver to use two pipes, nor the corresponding userspace code. It would actually be much easier to write a bonding driver to rule both IPv4 and IPv6 instances of the existing driver. It would also be more generic, not Phonet/CAIF/PPP-specific, although it would probably not work for fake Ethernet devices. However it is questionable why we would optimize this when the only customer is ConnMan, and the only use case is 3GPP Rel7. Applications don't need to care whether IPv4 and IPv6 are through a single or two separate interfaces. They just use the socket API. -- Rémi Denis-Courmont Nokia Devices R&D, Maemo Software, Helsinki _______________________________________________ ofono mailing list ofono@ofono.org http://lists.ofono.org/listinfo/ofono
