inux下原生ndis驱动及qmi lib探索
据说只要内核版本大于等于3.4即可使用原生高通ndis驱动，这让我兴奋了很久，终于不用自己写驱动，改bug了。于是，从网上下载了ubuntu14.04版本，并将它安装到了自己的pc上。
驱动：
qiao@qiao-Lenovo-Product:~$ cd /lib/modules/3.13.0-24-generic/kernel/drivers/net/usb/
qiao@qiao-Lenovo-Product:/lib/modules/3.13.0-24-generic/kernel/drivers/net/usb$ ls
asix.ko cdc_ether.ko cdc_subset.ko hso.ko kalmia.ko net1080.ko r8152.ko sierra_net.ko usbnet.ko
ax88179_178a.ko cdc_mbim.ko cx82310_eth.ko huawei_cdc_ncm.ko kaweth.ko pegasus.ko r815x.ko smsc75xx.ko zaurus.ko
catc.ko cdc_ncm.ko dm9601.ko int51x1.ko lg-vl600.ko plusb.ko rndis_host.ko smsc95xx.ko
cdc_eem.ko cdc-phonet.ko gl620a.ko ipheth.ko mcs7830.ko qmi_wwan.ko rtl8150.ko sr9700.ko
加载驱动
qiao@qiao-Lenovo-Product:~$sudo modprobe qmi_wwan
匹配设备pid/vid
qiao@qiao-Lenovo-Product:~$
sudo echo 1c9e 9b01 > /sys/bus/usb/drivers/qmi_wwan/new_id
检查驱动是否加载成功
qiao@qiao-Lenovo-Product:~$ ls /dev/cdc*
/dev/cdc-wdm0

安装完成，先读一个imsi号看看：
qiao@qiao-Lenovo-Product:~$
sudo qmicli -d /dev/cdc-wdm0 --dms-uim-get-imsi
[/dev/cdc-wdm0] UIM IMSI retrieved:
IMSI: '460110580947046'
qiao@qiao-Lenovo-Product:~$
sudo qmicli -d /dev/cdc-wdm0 --dms-get-capabilities
[/dev/cdc-wdm0] Device capabilities retrieved:

Max RX channel rate: '100000000'

还可以debug qmi 消息：
qiao@qiao-Lenovo-Product:~$
sudo qmicli -d /dev/cdc-wdm0 -v --dms-uim-get-imsi

关于wds--拨号控制
root@qiao-Lenovo-Product:~#
qmicli -d /dev/cdc-wdm0 --wds-start-network=cnnet
[/dev/cdc-wdm0] Network started

在openwrt上配置使用ndis拨号
在ubuntu下拨号成功后，再看一下openwrt下的qmi_wwan和uqmi表现---基线版本为14.04；
首先使能qmi配置：
CONFIG_PACKAGE_kmod-qmi-wwan=m --内核
CONFIG_PACKAGE_kmod-usb-wdm=m --内核
CONFIG_PACKAGE_uqmi=m ---system
配置network config：
root@OpenWrt:/# vi /etc/config/network
config interface 'wan'
option device '/dev/cdc-wdm0'
option proto 'qmi'
option apn 'cnnet'
option username 'card'
option password 'card'
option ifname 'wwan0'
重启
然后：ifup wan
拨号成功：
