wifi驱动移植
                               1、在终端通过wireless-tool 可以加载驱动，加载网卡，加载网卡时候有个错误（dhd_preinit_ioctls wl ampdu_hostreorder failed -23）
                               2、在终端可以扫描到周围热点，也可以连接上，通过udhcp -i 可以获取到ip，可以ping 通手机热点。
                               3、在上层，android界面可以看到扫描到热点，也可以连接上（通过打印可以连接上），通过dhcp获取ip也正常。
                               4、android界面一直是获取ip，就断开，然后在扫描，连接，获取ip，在断开 ，循环 

log 内容包括
         1、驱动的加载的log
         2、网卡启动的log
         3、手动启动dhcp -d 时候的log （底层驱动打印的，上层打印的）
         4、通过界面连接启动时候android上层的打印

Hi  xiaoliang

for porting driver you may wish to request direct support from vendor

Hi,

What's your kernel version?
