From acedce1d79e238be7ad8fcd8f82ef5a7db0bc929 Mon Sep 17 00:00:00 2001 From: Thomas Equeter Date: Thu, 16 Aug 2018 21:39:05 +0200 Subject: uqmi: wait for the control device too The control device /dev/cdc-wdm0 is not available immediately on the D-Link DWR-921 Rev.C3, therefore the wwan interface fails to start at boot with a "The specified control device does not exist" error. This patch alters /lib/netifd/proto/qmi.sh to wait for network.wwan.delay earlier, before checking for the control device, instead of just before interacting with the modem. One still has to use network.wwan.proto='qmi', as the "wwan" proto performs that sort of check before any delay is possible, failing with a "No valid device was found" error.
