Subject: Re: [PATCH net-next v6 0/3] The huawei_cdc_ncm driver / E3276
 problem

I am sorry: no ideas on what to do next. Still, one idea would be to try 
reverting these patches and see if it works with the original cdc_ncm driver, 
and see what happens.
Other than this, I do not have this device at hand, so can't see what happens. 
>From the version number, I expect the firmware being HiSilicon (not Qualcomm).
Try also using dhcpcd if you can / want / like :) .
Thank you.
