在安装redhat时，总遇到rhine网卡速度慢的问题。已经解决过多次，但每次不写记录，最后还要再找很长时间
，今天再次解决，不得不记下。
网卡型号：via vt6104 rhine-ii
操作系统：redhat AS 3.0(Taroon)
安装后，可自动发现网卡，但是速度奇慢无比。ftp只能达到20kb.不能忍受之，更新驱动。
从via_amd光盘找到via rhine网卡的linux的驱动rhinefet-4.17.tar.gz包。
上传到rhas3服务器/tmp/lan目录下
tar zxvf rhinefet-4.17.tar.gz
cd rhinefet-4.17.tar.gz
当然，此前由于网上错误教程的指导，曾把gcc的版本更换，要先检查gcc版本
gcc -v
确定是系统要求的gcc 3.2.3后，编译
make install
编译时出现冲突，不能成功。

不怕，仔细看一下就行了，是说/usr/src/linux-2.4/include/irda/irda.h中的
有两个冲突项ASSERT 与 LINK_STATUS，将两段注释了，编译即可通过。
#define ASSERT(expr, func) \
if (!(expr)) do { \
func } while (0)
typedef enum {
STATUS_OK,
STATUS_ABORTED,
STATUS_NO_ACTIVITY,
STATUS_NOISY,
STATUS_REMOTE,
} LINK_STATUS;
insmod rhinefet
shutdown -r now
之后网络速度变快。
一定要记得把/usr/src/linux-2.4/include/irda/irda.h中两段注释还原啊。
