Huawei E3131 and the ignored at^ndisdup command

[Enrico Mioso]

Hi !! Sorry for my late answer - a little bit busy here :) !

So - to be sure to understand what you're asking me, I try to explain myself 
better.
When I send dhcp requests on the wwan0 interface, I have absolutely no answer, 
so guessing this isn't a Hi-Link modem. Even tried with the mac-setting trick I 
applied with my E173, with no success, due to the ncm driver refusing to set a 
mac address! :)

About the ^ndisdup command: I was reporting it that way only to be short in 
form, but... yes, I tried it in both forms.
I also checked carefully the authdata structure to be configured properly, but 
then discovered the modem completely ignores it! :)

I'm so grateful for your help. Here some snippets:

In the meanwhile, I'm continuing to work on the cdc_ncm thing. I'm slo, I know
