Re: [PATCH v2 1/4] SARA R4 QMI support

[Jonas Bonn]

[-- Attachment #1: Type: text/plain, Size: 3005 bytes --]

Hi Jupiter,

Please add a description to your patch.  Something along these lines:

This adds support for the uBlox SARA-R4 modem.

Unlike other uBlox devices, this modem is actually a Qualcomm part and 
therefore supports the QMI protocol.  For that reason, this doesn't just 
jack into the usual uBlox modem framework.

The modem has a quirk in that it fails to reconnect to the network if a 
NAS detach is issued when connectivity is lost; therefore, we need to 
add some 'vendor' handling to the QMI gprs atom to account for this.

This has been tested... how?

Hope that helps,
Jonas

Assuming you've tested this, you'll know whether 'attach' is required or 
not.  As such, fix accordingly and remove the above comment.
