Hi Aleksander,

that's interesting, even if I am not sure about what/where to look for more
information.
I was looking into network subinterfaces, starting from this discussion on
the mailing list

    [PATCH 1/2] broadband-modem-mbim: allow "max_sessions" bearers
<https://lists.freedesktop.org/archives/modemmanager-devel/2014-June/001187.html>

is this the correct direction?

BR,
Carlo
