Hey Matthew,
I reviewed the first patch of the series only for now; let's try to get
this right first and then we go on with the other ones. See comments
inline below. Some of the comments are coding style only things, but
others try to simplify or change the flow of the logic, let me know what
you think.

You're not supposed to "paste" the patch in the email body or "merge"
the patches in a single file and attach them to the email :) The target
is that we can take the patches and quickly apply them with "git am"; if
you paste the patch in the body it's likely that your email application
may decide to modify the body before sending it; if you merge patches
together in a single file, "git am" may end up choking when processing it.
Sending patches can be done in 3 different ways:
a) Use git-send-email command line tool, this will generate emails
that can then be saved and applied with "git am".
b) Use git format-patch and generate 1 file per patch; then attach the
patches to the email. Again, we can use "git am" to apply them.
c) Prepare a custom branch somewhere; e.g. bitbucket or github, and
email the link to the branch so that we can pull from it.
For reviewing, I usually prefer a), and if too complex to setup, just do
b). For large developments c) is preferred, though.

Reviewing logic is very very hard with commits including different things :/

Cinterion did send me a test-only PLS8 to play with the QMI integration
they had, but not sure if they're still targeting to use QMI or not.
See comments for the first patch below.

I think it should be better to have separate Connect/Disconnect contexts.

This should be a uint.

Retry count looks like part of the connection/disconnect logic;
shouldn't it go in the connect/disconnect context?

The connect/disconnect logic should have different contexts, and then
the complete_and_free() names could match the context name.
E.g. Connect3gppContext with connect_3gpp_context_step() and
connect_3gpp_context_complete_and_free ().

Coding style thing; we don't use "//" ever, not even for single-comment
lines. Use /* this instead */. Applies to multiple places in the code.

What is the purpose of this method if it's just ref-ing the passed
primary port? Why not just "g_object_ref (primary)" in the caller?

This step just wants to get to the next step. So just do ctx->connect++;
and fall down to the next case without a break; E.g.
case CONNECT_3GPP_CONTEXT_STEP_INIT:
ctx->connect++;
/* fall down */
case CONNECT_3GPP_CONTEXT_STEP_VERIFY_SWWAN:
....

The {} for the case is only really needed if you're going to define
variables within the case clause; I would remove those otherwise.

Just set the new step to run and call connect_3gpp_context_step (ctx);
directly. E.g.:
if (...) {
ctx->connect = NEXT_STEP;
connect_3gpp_context_step (ctx);
return;
}
if (some other thing) {
ctx->connect = SOME_OTHER_NEXT_STEP;
connect_3gpp_context_step (ctx);
return;
}

If this is impossible to get here, just g_assert_not_reached(); don't
return an error to the caller if this is a programmer error.

No, this is not right, usb0 and usb1 are network interface names that
the kernel decided to use; what if you have 2 Cinterion modems at the
same time?
Instead of relying on the interface name, you may want to rely on the
USB interface number; e.g.
g_udev_device_get_property_as_int (
udev_device,
"ID_USB_INTERFACE_NUM")
NOTE: you'll need a GUdevDevice for the WWAN; which you could get using
a new GUdevClient. This will be much easier to handle once the work I'm
doing to allow skipping udev is integrated, as then you can just get a
MMKernelDevice from the MMPort and query the property directly, like:
mm_kernel_device_get_property_as_int (
mm_port_peek_kernel_device (port),
"ID_USB_INTERFACE_NUM");
See e.g. this similar case in the Huawei plugin:

You could have a single if() to catch the error case, and then do the
ctx->connect++; and /* fall-down */ thing to get to the next case.

This connect_3gpp_context_step() wouldn't be needed as each case above
should call it itself when needed and directly return.

Never never ever just sleep() :) If you need to reschedule the same step
in 1s, you should:
g_timeout_add_seconds (
1,
(GSourceFunc) cinterion_3gpp_state_machine_logic_reschedule_cb,
ctx);
return;
And then implement the callback:
static gboolean
cinterion_3gpp_state_machine_logic_cb (Control3gppContext *ctx)
{
cinterion_3gpp_state_machine_logic (ctx);
return G_SOURCE_REMOVE;

Nothing should call this, yet there is an explicit step selection for
this one some lines above... :)

As for the connect logic, I think it's better to just call the
context_step() method directly after setting the next step, not doing a
break; and a single context_step() here. This is because each step will
be auto-contained within the case(), I think it helps readability of the
state machine.

I see this logic mixing connect/disconnect again; I think we shouldn't
do this. If the SWWAN response is parsed in the same way for both,
better write a parser method and let the different connect/disconnect
flows call it.

Too complex, too complex :). If you had one logic for connect and
another logic for disconnect, you could pass around the actual Context
struct in the async calls user_data, which holds already a reference to
the bearer object. Instead, you're storing the contexts in private info
and passing the bearer object.
It is good to store the connect and disconnect contexts in the private
info ONLY if there is no other place to manage them. If the logic relies
on queries to the modem to check e.g. SWWAN status, you can pass around
the contexts in the async calls and not ever store them in private info.
One of the good reasons to store the context in private info is when you
rely on unsolicited messages from the modem. For your use case, I think
you could totally avoid storing the contexts in private info, and the
logic would be much much simpler. What do you think?

But proccess_swwan_response() doesn't set a GError to return here if it
fails.

You would never need a g_clear_error() here if errors are propagated
earlier whenever they happen.

Will this run the same state machine step again? I think it is usually
more clear to update the step to run, and then call the state machine
logic, something like:
ctx->step++;
context_step (ctx);

Just remove this return; :)

This is much better than returning a blind GList of integers where the
caller needs to know which integer is which:
gboolean
mm_cinterion_parse_swwan_response (
const gchar *response,
guint *cid,
guint *state,
guint *wwan_adapter,
GError **error);
Also, please write unit tests for the newly written parsers.
