OK6410A移植mw150us无线网卡驱动

一 ubuntu 12.04移植mw150us驱动
参考：
1）https://blog.csdn.net/wangdapao12138/article/details/82559422
2）https://www.cnblogs.com/zfyouxi/p/5279940.html
3）https://github.com/kuba-moo/mt7601u/issues/64#issuecomment-352250127
4）https://forum.ubuntu.org.cn/viewtopic.php?p=3211381

问题：
1）根据参考1）编译mt7601u的源码时提示
ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.
原因：没有编译内核
make oldconfig
make prepare
make scripts

2）加载驱动时提示：insmod: error inserting 'hello.o' :-l invalid module format错误
网上说是内核版本不匹配导致

3） 错误： 将‘kuid_t’赋值给‘int’时类型不兼容
原因：内核在3.x以上后移除以下定义
typedef uid_t kuid_t;
typedef gid_t kgid_t;
只剩下如下定义
typedef struct {
uid_t val;
} kuid_t;

typedef struct {
gid_t val;
} kgid_t;
所以需要将用到kgid_t、kuid_t的位置修改kgid_t.val、kuid_t.val的结构体的使用

4）nfs经常掉线
mount -t nfs -o nolock -o tcp 192.168.0.200:/home/ros/ok6410/debian_arm /mnt

5)insmod 网卡驱动后，使用ifconfig -a可以看到新增的网卡驱动，但是没法使用，
使用ifconfig myWlan0 up显示ifconfig: SIOCSIFFLAGS: Operation not permitted
使用dmesg | tail -50

移植步骤归纳(ubuntu 12.04 x32)：
1）插上mw150us无线网卡后，在ubuntu查询网卡ID与厂商：
ros@ros-virtual-machine:~$ lsusb
Bus 001 Device 002: ID 148f:7601 Ralink Technology, Corp.
根据上面命令得知mw150us的ID为148f:7601，厂商为Ralink，在百度上搜索Ralink 7601发现刚好有Ralink
MT7601U类似的信息，所有直接下载MT7601U的源码进行尝试编译安装(后面证实确实是这款芯片)，
而且在https://www.mediatek.com/products/broadbandWifi/mt7601u上有MT7601U的源码。

2)解压源码，
打开include/rtmp_def.h 文件修改网卡名称，这里修改为testWlan：
#ifdef ANDROID_SUPPORT
1601 #define INF_MAIN_DEV_NAME               "wlan"
1602 #define INF_MBSSID_DEV_NAME             "wlan"
1603 #else
1604 #define INF_MAIN_DEV_NAME               "testWlan"
1605 #define INF_MBSSID_DEV_NAME             "testWlan"
1606 #endif /* ANDROID_SUPPORT */

修改Makefile文件：
修改平台为SMDK,
#PLATFORM = PC
PLATFORM = SMDK

修改内核源码路径（这里是/home/ros/robot-linux/linux-3.0.1）和交叉编译器：
ifeq ($(PLATFORM),SMDK)
LINUX_SRC = /home/ros/robot-linux/linux-3.0.1
CROSS_COMPILE = arm-linux-
endif

3）make clean
     make -j 4
     完成后os/linux目录下生成了mt7601Usta.ko

4）将网卡驱动源码目录下的  RT2870STA.dat文件和生成的mt7601Usta.ko拷贝到开发板上；
5）将 RT2870STA.dat文件拷贝到开发板的/etc/Wireless/RT2870STA/目录下
mkdir -p /etc/Wireless/RT2870STA/

6）修改开发板上/etc/wpa_supplicant.conf文件：
network={
        ssid=热点名称
        key_mgmt=WPA-PSK
        psk=热点密码
}

7）insmod mt7601Usta.ko
8）ifconfig -a，可以看到
testWlan0 Link encap:Ethernet  HWaddr 00:00:00:00:00:00  
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

9）ifconfig testWlan0 up开启网卡
10）连接无线网络：wpa_supplicant -B -c /etc/wpa_supplicant.conf -i testWlan0
11）查看连接状态：wpa_cli -i testWlan0 status
12）配置网卡ip地址，这里直接使用动态分配：udhcpc -i testWlan0
