A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.-A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running comput

本实验将实现如下功能：本实验利用STM32F10开发板上的DM9000网络芯片实现联网功能，网络协议栈使用的LWIP,版本为1.4.1。默认开启了DHCP，将开发板连接到路由器上以后就会自动获取IP地址，当DHCP失败以后就会使用默认IP地址，默认IP地址为：192.168.1.30。DHCP成功后就可以在电脑上通过ping命令来测试LWIP移植是否成功。
