On small systems with many virtual devices, the modem manager sometimes
could not start because it took too long until all devices for the modem
were recognised. This is because all system events that are stored in
the file events.cache have to be processed. To speed up the processing,
all devices under /sys/devices/virtual are now filtered out so that they
do not have to be processed.

OpenWrt ModemManager
Description
Cellular modem control and connectivity
Optional libraries libmbim and libqmi are available. Your modem may require additional kernel modules and/or the usb-modeswitch package.
Usage
Once installed, you can configure the 2G/3G/4G modem connections directly in /etc/config/network as in the following example:
config interface 'broadband'
option device '/sys/devices/platform/soc/20980000.usb/usb1/1-1/1-1.2/1-1.2.1'
option proto 'modemmanager'
option apn 'ac.vodafone.es'
option allowedauth 'pap chap'
option username 'vodafone'
option password 'vodafone'
option pincode '7423'
option iptype 'ipv4'
option lowpower '1'
option signalrate '30'
Only 'device' and 'proto' are mandatory options, the remaining ones are all optional.
The 'allowedauth' option allows limiting the list of authentication protocols. It is given as a space-separated list of values, including any of the following: 'pap', 'chap', 'mschap', 'mschapv2' or 'eap'. It will default to allowing all protocols.
The 'iptype' option supports any of these values: 'ipv4', 'ipv6' or 'ipv4v6'. It will default to 'ipv4' if not given.
The 'signalrate' option set's the signal refresh rate (in seconds) for the device. You can call signal info with command: mmcli -m 0 --signal-get
