RT3070移植到tp 703N

第一次尝试驱动的移植可谓真的是不容易啊，现在记录一下我所遇到的问题。

opwnert我是使用turn R4558

  一、在官网http://www.mediatek.com/下载了DPO_RT5572_LinuxSTA_2.6.1.3_20121022然后按照readme的方法修改。然后编译最后在os/linux中得到RT3070。KO的驱动模块。加载到内核中。使用iw命令都可以查看到WIFI的信号，但是就是在luci中找不到这个网卡的接口。到现在都没有办法解决。

使用wifi  detetc>/etc/config/wireless都不能重新生成接口的配置，使用iwconfig命令得到

ra0    ralink sta这个明显的不对啊，应该是ra0 ieee80211 等等才可以使用wifi命令重新配置wireless啊。。无赖看不懂驱动程序。不知道怎么修改

二、没有办法了只用使用openwrt自带的驱动了（rt2800 rt28xxlib）。（编译内核模块的时候添加进来就OK了）。

三、在使用自己编译的驱动或者使用自带的驱动都会有一个问题。在插入usb网卡之后可以正常识别网卡并驱动。但是使用ifconfig ra0 up的时候，查看内核日志（dmesg）发现usb断开了连接，然后又立马连接上。一下是我打印的信息

一开始怀疑是USB接口的供电不足。在网卡芯片的处从新接入一个5v还是不行。无赖只有不使用网卡自带的10m usb延长线，终于0K了。

我分析应该是AR9311usb接口驱动能力不足。没有加入驱动芯片。等有时间重新改造一下这个usb接口

最后一步了。使用RT3070链接一个信号很弱的wifi（AP clent模式）.命名为TP接口。使用AR9311自带的wifi作为mast模式作为AP。（）接口选择默认的lan接口。。

就可以实现usb网卡连接其他人的wifi。AR9311在转发出来。。
