linux9.0 vmware配置网卡不能起的bug：
简单的说这是vmware虚拟网卡的bug，RH9包含检测网卡状态的脚本，但是在vmware下总是返回"link down"，解决方法如下：
 On Mandrake 9.1 add
 NO_MII_SUPPORT=yes
 to /etc/sysconfig/network-scripts/ifcfg-eth0.

 On RedHat 9 add
 check_link_down() {
 return 1;
 }
 to the same file (just write it as is, Redhat fortunately allows functions in their config files...).
