qmicli and IPv4 / IPv6

Hi !
I analyzed the original firmware yesterday evening and also found this. I extended qmicli with a IP family patch
to add this this to the start-network command.
I tried to implement it like it is done with uqmi (the original openwrt qmi client) like this:
------------
CID1=$(qmicli -p -d /dev/cdc-wdm0 --wds-noop --client-no-release-cid|grep CID|cut -d\' -f2)
qmicli -v -p -d /dev/cdc-wdm0 --wds-start-network=apn=internet.t-mobile,family=4 --client-cid=$CID1 --client-no-release-cid
CID2=$(qmicli -p -d /dev/cdc-wdm0 --wds-noop --client-no-release-cid|grep CID|cut -d\' -f2)
qmicli -v -p -d /dev/cdc-wdm0 --wds-start-network=apn=internet.t-mobile,family=6 --client-cid=$CID2 --client-no-release-cid
------------
But qmicli gives me a POLICY MISMATCH error where uqmi works. I traced the writes to the the qmi device and
saw the following differences:
uqmi
3304 write(4, "\1$\0\0\1\10\0\2\0 \0\30\0\24\21\0internet.t-mobile\26\1\0\3", 37) = 37
qmicli
3415 write(5, "\1$\0\0\1\n\0\1\0 \0\30\0\31\1\0\4\24\21\0internet.t-mobile", 37) = 37
But I was not able to translate that back to the original commands. Do you have an idea?
I'll append the full log of it.
Here's my alpha patch of familiy support for qmicli:

If you have an idea why this policy mismatch happens I would appreciate it. I prefer qmicli over uqmi
because it is still improved and has the proxy integrated.
Kind regards,
André
