[07/10] gobi: Support RAW_IP configuration

Commit Message

Denis Kenzior Nov. 21, 2024, 3:29 p.m. UTC

Most newer QMI modem firmware only support RAW_IP based configurations.
This is a more efficient data path since 802.3 headers do not need to be
emulated.  Support this data format by configuring the 'raw_ip' setting
on QMI_WWAN accordingly.
