Hi there!

I noticed this regression today after upgrading to trunk. I don't think
this is the complete answer though.

I have the same E3276 dongle and I *do* have IPv6 from my ISP (Tele2,
Sweden). The same SIM-card in a B593s-22 router gets me a native IPv6
connection.

I see the exact same error in the logs and I've verified that E3276 doesn't
accept IPV6 (or IPV4V6, or ... ) as the second parameter by manually echo
-e 'AT+CGDCONT=1,"IPV6","internet.tele2.se",""\r' > /dev/cdc-wdm0. Only
"IP" works.

Is the AT+CGDCONT command the correct way to select the PDP type on Huawei
NCM dongles? What info is that based on?

If there's something you want me to try, just shout.

/Andreas
