[PATCH 00/19] Support for U-Blox Toby L2 modems

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 2132 bytes --]

This patchset adds support for Toby L2 modems in high throughput
mode.

Besides basic support, the following things are supported:
* bridged AND routed modes.
* LTE default bearers.
* Multiple primary PDP contexts.


Dongsu Park (4):
  plugins/udevng: support the U-Blox TOBY-L2 series
  plugins/udevng: support different interface strings to detect TOBY
    series
  plugins/ublox: read network mode
  ubloxmodem: add routed mode support

Dragos Tatulea (15):
  plugins/udevng: ublox: set model string
  include: vendor.h: add vendor for ublox toby
  plugins/ublox: allow enabling of TOBY L2 modems
  plugins/ublox: use vendor from structure instead of fixed
  atmodem: ublox: EPS now supported by newer ublox
  atmodem: add support for U-Blox TOBY L2 modems
  atmodem: work around CGREG issues in UBlox Toby L2
  ubloxmodem: add Toby L2 gprs context driver
  gprs-context.h: add function for setting APN
  gprs: allow APN updates from gprs-context driver
  ubloxmodem: push back APN into gprs context
  plugins/ublox: give names to model ids
  plugins/ublox: enable ubloxmodem driver when possible
  plugins/ublox: support more internet contexts
  ubloxmodem: support authentication

[PATCH 01/19] plugins/udevng: support the U-Blox TOBY-L2 series

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 831 bytes --]

From: Dongsu Park <dongsu@endocode.com>

The newest generation of U-Blox TOBY-L2 series can be detected with
VID 0x1546 (the same as before), and one of the following PIDs:

* "0x1146" : high throughput profile
* "0x1141" : fairly back-compatible profile
* "0x1143" : low/medium throughput profile

This patch adds detection for high throughput mode.

[PATCH 02/19] plugins/udevng: support different interface strings to detect TOBY series

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 2554 bytes --]

From: Dongsu Park <dongsu@endocode.com>

Each modem expresses their interfaces with its own interface string,
which is composed of 3 different USB attributes:
"bInterfaceClass/bInterfaceSubClass/bInterfaceProtocol".
While the old models like LISA support only "2/2/1" for modem
interfaces, TOBY-L2 also supports an unique string for NetworkInterface
for each profile.

* low-medium throughput profile : 2/6/0
* fairly backward-compatible profile : 10/0/0
* high throughput profile : 224/1/3

Besides the condition for checking NULL for mdm/aux/net should be relaxed
a little bit.

This is a pretty nasty hack specific for TI Calypso.  I wouldn't use it 
unless you really need it.

[PATCH 08/19] atmodem: add support for U-Blox TOBY L2 modems

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 3900 bytes --]

Besides exceptions below, act like normal U-Blox devices.

gprs-context: don't set auth for TOBY L2. U-Blox Toby L2
doesn't support PAP/CHAP APN auth method.

atmodem: TOBY L2 supports only CMER mode 1. Also chaged original
mode variable to ind, which is a more appropriate name.
mode is what is being set first.

Lets make this into a switch/case statement.

e.g. const char *mode;

switch (nd->vendor) {
case OFONO_VENDOR_UBLOX_TOBY_L2:
	mode = 1;
	break;
default:
	mode = 3;

[PATCH 09/19] atmodem: work around CGREG issues in UBlox Toby L2

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 2016 bytes --]

Don't use CGREG for network notifications. It will return
4 both when registered in LTE and in unknown state.

For the CGREG? query, interpret 4 as registered.

Does ublox support AT+UREG? ?  Perhaps that would be easier than making 
this hack.  The core polls gprs_driver->attached_status in various 
cases, so assuming that 4==1 here seems unsafe.

[PATCH 10/19] ubloxmodem: add Toby L2 gprs context driver

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 16912 bytes --]

For now the driver works only with bridged mode.

Once it activates the context it reads the ip, netmask,
gw, dns and sets them in the context settings.

4G default bearer is supported as well by reading the
automatic activation cid and using it in the first context
activation.

[PATCH 12/19] gprs: allow APN updates from gprs-context driver

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 2625 bytes --]

In the context activation callback, check for a changed APN. The default
PDP in a 4G network is usually automatically activated. We might not know
the APN. So allow the driver to read the APN and push it back into the
core context.

[PATCH 13/19] ubloxmodem: push back APN into gprs context

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 1637 bytes --]

It can be that the APN is different than what a user provided. So let
the core know. This happens for example when using the default bearer:
the user doesn't provide any APN, so read the one from CGCONTRDP.

Where possible means Toby L2 in high speed mode.

The bridge mode is set before enabling the modem because the

[PATCH 19/19] ubloxmodem: add routed mode support

[Dragos Tatulea]

[-- Attachment #1: Type: text/plain, Size: 5510 bytes --]

From: Dongsu Park <dongsu@endocode.com>

Routed mode needs a different treatment than bridged mode:

* UIPCONF needs to be used for reading the interface ip configuratuion.
The spec says that DHCP should work on that interface but it doesn't. So
we read the first ip in the dhcp range and use that.

* CGCONTRDP: only APN and DNS configuration is read

[PATCH 01/19] plugins/udevng: support the U-Blox TOBY-L2 series

[dragos]

[-- Attachment #1: Type: text/plain, Size: 831 bytes --]

From: Dongsu Park <dongsu@endocode.com>

The newest generation of U-Blox TOBY-L2 series can be detected with
VID 0x1546 (the same as before), and one of the following PIDs:

* "0x1146" : high throughput profile
* "0x1141" : fairly back-compatible profile
* "0x1143" : low/medium throughput profile

This patch adds detection for high throughput mode.
