Actually, the K3565-Z doesn't support QMI either :) It does have the possibility of a pseudo-ethernet port, but that's a custom implementation by ZTE's firmware team that isn't at all QMI related. Thankfully on the K3565-Z it's more or less standard and we don't have to go to the lengths to support it that we do for QMI-based devices. It appears the K3565-Z is based on the MDM6290 which is the same chipset that's in your Sierra 8790 :) Thus no QMI. (Technically QMI and pseudo-ethernet interfaces are completely unrelated, it just happens that every Qualcomm-derived device that supports QMI has the capability of a pseudo-ethernet interface even if the OEM's firmware team doesn't actually expose it.)
