Vodafone (ZTE) K3806-Z: Couldn't parse IPv6 address '255.255.255.0'
I'm trying to use a ZTE 3G key. That key is working well on a Fritz router.
Apparently everything works fine in the first steps (usb_modeswitch), and she is seen correctly by ModemManager/mmcli, even if the specific usb id (19d2:1015) is not listed in udev files.
But, when starting the connection I receive the error: "Couldn't parse IPv6 address '255.255.255.0'", and ModemManager closes the connection, even if the blue light on the key became solid blue, meaning good connection.
Apparently the problem is in the parsing of the %IPDPADDR command response. But the only place on the code where I was able to found reference of this error is in plugins/icera/mm-modem-helpers-icera.c, so the problem could also be generated by a wrong modem detection.
