-# 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
