This patch makes it possible to use MM to set up PDP contexts with
PDP types other than 'IP', which is particularly useful when trying
to use the 'IPV6' or 'IPV4V6' PDP types defined in recent 3GPP specs.
If ip-type isn't specified, 'IP' will be used by default, due to the
fact that modem support for the 'IPV4V6' type is still rather scarce.
The patch applies to Aleksander's 'bearer-properties' branch. It has
been tested using mmcli in this fashion:
mmcli -m 0 --simple-connect=apn=internet # default to 'IP'
mmcli -m 0 --simple-connect=apn=internet,ip-type=IP
mmcli -m 0 --simple-connect=apn=internet,ip-type=IPV6
mmcli -m 0 --simple-connect=apn=internet,ip-type=IPV4V6
