You can get a PolicyMismatch error even if you have a dual-stack
profile, if you try to create a dual-stack connection without using the
"Set IP Family" request to toggle between IPv4 and IPv6.  Using the
"IP Family Preference" TLV during connect is not sufficient.

I hit this recently when trying to create a dual-stack connection on a
Huawei E392 using qmicli.

There hasn't been any changes to how MM will create dual-stack QMI
connections recently?
