奇怪的网卡问题！！！
[code]
AierM:/home/tmeng# uname -a

在PCMICA插槽中有一块DECchip 21143芯片的网卡；从得到的信息来看，驱动已经加载了；并且所加载的驱动也包含 本芯片型号；如下：

但问题还是意外的发生了，找不到所标识的eth1网卡，如下：
[code]
AierM:/home/tmeng# ifconfig eth1
eth1: error fetching interface information: Device not found
AierM:/home/tmeng# ifconfig

AierM:/home/tmeng# ifconfig eth1 up
eth1: ERROR while getting interface flags: 没有那个设备
[/code]
上面输出的eth0为集成的板载网卡，e1000的，可以看到MAC地址与eth1是不同的。
在插入网卡或重加载模块的过程中可以看到：

上面显示eth1已加载，芯片型号和MAC地址均无误，可ifconfig输出就是没有，真是无比郁闷 ：（：（：（

真是邪门了，百般无耐，处到翻看，Google无数，均无答案
终查看/pro/net/dev ,有些线索，如下：
[code]

[/code]
乖乖，不是有个eth3吗,赶紧 up先，如是那朵出色的tulip终于出来了，如：
[code]
AierM:/home/tmeng# ifconfig eth3 up
AierM:/home/tmeng# ifconfig eth3
eth3 Link encap:Ethernet HWaddr 00:80:4C:35:0D:78

[/code]
但比较让我郁闷是的，为什么不是默认的eth1而是eth3呢？继续找找看，是什么原因
