S3C2440移植RTL8187L无线USB网卡记录(未解决)

首先准备了一大轮，最後还是有问题。

内核准备，2.6.13(S3C2440准备好)，支持USB设备、WIFI等。

网卡驱动的移植，编译什麽不费多大劲，CC、LD、CFLAG等的改几下。

然後，找一个dhcp(dhcp-3.1.3)，其实只要当中的client。make -C=arm-linux-gcc。

iwconfig wlan0 poweron on
iwconfig wlan0 mode managed
iwconfig wlan0 rate auto
iwconfig wlan0 ap 00:18:4d:7e:e0:74
iwconfig wlan0 essid shuangxi
iwconfig wlan0 key off

dhclient wlan0

注意：虽然工作顺利，但未成功的。
