This patch adds support for QMI to netifd. It enables netifd to access the
network functions of several 2G/3G/4G sticks. For usage of qmi, the device has
to support 2 functions:
-cdc-wdm interface for control
-wwan interface for data
Throuput should also be a lot better than through serial and pppd. To use this,
you should have a stick like a Huawei E392. It is configured through
/etc/config/network. Example:
config interface 'broadband'
option ifname 'wwan0'
option proto 'qmi'
option pincode '1234'
option apn 'web.vodafone.de'
option username 'user'
option password 'password'
# if you want a sepearate LTE APN to be used, set
option lte_apn_use '1'
option lte_apn 'web.vodafone.de'
option lte_username 'user'
option lte_password 'password'
Stability is watched via a small watchdog, which does arp to check if modems
still
responds. To be able to use username and password authentication, latest libqmi
is
needed. Because I have no IPv6 enabled cellphone provider, this is not tested.
Any ideas are welcome!
Thanks to Aleksander Morgado for his great work!
