Unfortunately I have no idea why you see that, and I cannot reproduce any such issues with any of the modems I have. I don't remember - did you already send me packet dumps of these issues? If not, then please do. But there is no need to hurry - I don't think I'll have any chance to look at it this year. > Unfortunately I can not test IPv6-behavior at the moment. > (the agreement was limited, I am not sure, if I get a new one) Luckily I've now got a few SIM cards with IPV6 enabled subscriptions so I am able to test on the modems I have. I cannot make it work with any NCM modem though, which I admit is a bit suspicous. Now I don't know if and how it may have worked before, and I'm not at all convinced that the old firmware revisions I have ever really supported IPv6 properly. Or I'm just failing to understand how they are supposed to be configured. The modems connect fine, but I cannot get any global address config out of them using AT commands, RS or DHCPv6 solicits. Anyway, I should probably go back a few kernel versions and verify that I cannot make these NCM modems work with IPv6 there either. FWIW, my QMI (MC7710, E392) and MBIM (MC7710, DWM-156) modems all work fine with v3.13-rc3 and IPv6, except for the Huawei E367 which doesn't support IPv6 PDPs at all (at least not with the firmware revision I have). None of the modems seem to respond to DHCPv6 solicits. The MC7710 and E392 support RS/RA. All support management protocol address configuration. Which should be the default for MBIM in any case, given that it is a standard part of the protocol and the DHCP and RA daemon in modem firmware is a really ugly hack.
