Most Sierra PPP-based devices are supposed to allow PPP on the
APP1 port, which has a dumb AT parser, leaving the main port
(with the intelligent AT parser) free for status and signal strength.
But out of all the devices I've tested it with (8775, 8781, AC881,
and C885), only the C885 actually works. The rest (including three
different firmware versions for the 8775) either crash or disconnect
shortly after PPP starts.
To help figure out which devices actually support this, when
running MM in debug mode, users can set the MM_SIERRA_APP1_PPP_OK
environment variable and assume the APP1 port allows PPP. This
is only for debugging purposes.

sierra: fix CSQ handling on APP1 port
The APP1 port doesn't always prefix its replies with <CR><LF> which
runs afoul of the built-in echo removal. Since Sierra modems are on
the whole well-behaved WRT echo removal, just disable it on the
secondary ports. Only changes behavior for PPP-based devices since
they are the only ones that use the APP1 ports.

sierra: use DHCP for the USB 305 (AT&T Lightning)
For some reason, my AT&T Lightning just doesn't work with static
IP (AT%IPDPADDR) any more. No traffic passes even though everything
is set up the way it was before. No idea what happened. Using
latest firmware 2.0.0.11.
But what's interesting is on Windows the generic Sierra Watcher
app uses DHCP. But on Linux, when using AT%IPDPACT, DHCP doesn't
work. That's odd. But it turns out the modem supports the
"standard" Sierra proprietary AT!SCACT commands, and that
*does* make DHCP work. Crazy no? So since the Windows app
uses DHCP, it's likely that the non-DHCP case (AT%IPDPACT/AT%IPDPADDR)
either isn't well tested or isn't well supported. With that
in mind, let's just use DHCP for this device in Linux too.

icera: handle additional IPv4 configuration options
Newer devices like the ZTE/Vodafone K3805-z have an enhanced
%IPDPADDR command that includes a netmask and gateway, and
these are necessary to configure the device since it uses /24
instead of a /32. Since the device is nice enough to tell
us that, we should probably use that information.
Unfortunately the MM API doens't expose the netmask and gateway
yet, so we'll have to add a GetIP4ConfigEx() method or something
like that, but this commit sets us up to do that.

zte: handle Icera-based devics that use DHCP
Since we can't autodetect that the devices use DHCP, we'll need to
tag them with udev rules for the time being.

Some Sierra modems (e.g. MC7710) will report LTE-specific supported modes in the
AT+WS46=? reply, but not +CLTE capability in the AT+GCAP reply:
AT+GCAP
+GCAP: +CGSM
OK
AT+WS46=?
+WS46: (12,22,25,28,29)
OK

novatel: fix checking ERI for roaming/home decision

icera: retry configuring PDP context if it fails.
If a connect operation is attempted immediately after a disconnect,
it sometimes fails with CME error 583 - "a profile (CID) is currently
active". Apparently, even though the preceding operation (%IPDPACT)
to deactivate the PDP context returned an OK response, the context
is not really completely available until a fraction of a second
later. This causes the %IPDPCFG operation that is part of the
subsequent connect attempt to fail with error 583. This change
retries the %IPDPCFG after a one second delay.
BUG=chrome-os-partner:4936
TEST=This can be tested from the UI, but I found it easier to produce
the timing needed to trigger the bug by running mm-disconnect and
mm-connect from a shell.
Start out with the modem in the connected state. In the shell, run
sudo /usr/local/lib/flimflam/test/mm-disconnect; sudo /usr/local/lib/flimflam/test/mm-connect --number='*99#' --apn=wap.cingular
modem-manager should emit the log line "Invalid error code: 583".
Prior to this change, the connect operation would fail. Now it should
succeed.

sierra: fix detection of APP1 port
The APP1 port (which has a limited AT parser) doesn't prefix
its replies with <CR><LF> like nice modems do, and that means
it runs afoul of the echo removal bits of the AT serial port
code. We need to parse the whole string even though it's not
prefixed properly to find the APP1 string in the response.

We were using the slice allocator, not plain g_malloc().

|
|
|
|
|
Some sierra modems (e.g. MC7710) have a secondary port that likes to reply OK
to any AT command passed. Detect that as soon as possible, and don't consider
the Icera port probing result from that secondary port.
|
|
GErrors need to be always NULL initialized.

Based on empirical results, 'AT+CRSM=176,28423,0,0,9' is found more reliable
than 'AT+CIMI' for reading IMSI.

Seems the reply to the command is received once the change has been done, so it
may take longer than the previous default of 3s.

Different ports of the same modem may get handled by different drivers. We
therefore need to provide a list of drivers (new `Modem.Drivers' property with
signature 'as') instead of just one (removed `Modem.Driver' property with
signature 's').
$ sudo mmcli -m 0 | grep drivers
| drivers: 'qcserial, qmi_wwan'
|
|
|
|
|
|
Commands treated as 'raw' won't get the 'AT' prefix and will also not get the
trailing carriage return.
