Dear All,
I currently add supprt for the dwr-512 device on LEDE.
This device have a 3G modem embedded.
The current available configuration uses the usb-option to establish the 3G
connection over ppp.
Nevertheless the modem offer one cdc-ether interface with better
performance.

It seems to me that currently this kind of "protocol" is not supported in
LEDE.
In particular I'm unable to found an interface type in the
/etc/config/network to setup this kind of connection.
Currently I'm able to establish a connection setting the interface in
"manual" mode.
To do this I setup an usb interface
config interface 'wan3g'
option ifname 'usb0'
option proto 'dhcp'
then I need to send manually the following command to the /dev/ttyUSB0 to
establish the 3G connection:
AT+CFUN=1
AT+CPIN="<SIM PIN>"
AT+CREG?
> +CREG: 2,1,"1CE3","0BCA3360",6 (6=UTRAN w/HSDPA and HSUPA)
AT+CGDCONT=1,"IP","<APN>",0,0
AT+CGACT=1,1
AT+CGACT?
AT+CGPADDR=1
>> +CGPADDR: 1, "109.42.15.170"
AT+CGPRCO?
>> +CGPRCO: 1, "139.7.30.126", "139.7.30.125", "", ""
AT+CGDATA="M-MBIM",1,1
at this point the IF is UP and working:
usb0 Link encap:Ethernet HWaddr 02:00:FF:AA:AA:AA
inet addr:109.42.15.170 Bcast:109.42.15.171 Mask:255.255.255.252

Can someoune help me in introduce the handling of this "protocol" in LEDE?
Thanks,
Bye.
