This is, no DHCP at all here. If the kernel doesn't support raw ip, and we find a QMI network interface configured to use raw-ip by default, we *try* to switch it to 802.3 mode, either with the "net-802-3" flag when opening the device or via WDA operations. I say *try* because not all modems allow switching (e.g. MC7455 won't). If we can successfully switch it to 802.3, we then use DHCP on the interface. In your case, I believe this Pantech modem should definitely allow 802.3. Maybe try with --wda-set-data-format? -- Aleksander https://aleksander.es
