uqmi: fix raw-ip mode for newer lte modems
Some newer LTE modems, like the MC7455 or EC25-E do not support "802.3" mode, and will stay in "raw-ip" regardless of the mode being set. In this case, the driver must be informed that it should handle all packets in raw mode. [1] This commit fixes connectivity issues for these devices.
