From bc2f3a2830b0066d1aab77c7a27aafb21f3529ca Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 28 May 2014 19:45:20 +0000 Subject: [PATCH] uqmi: Add support for QMI-based mobile broadband modems Many of the 4G/LTE and 3G modems utilize the QMI-protocol to control the modem. At the moment there is no support for them in OpenWrt. This patch adds support for them in the form of a netifd script and a control utility. Tested with Huawei E398 and ZTE MF820D (which requires a delay of ~30 s before responding to QMI commands). I put myself up as the maintainer, feel free to change this if you desire.
