CentOS网卡显示为__tmpxxxxxxxx

一台服务器做了2组端口绑定（bonding），其中一组bond总是不成功，发现少了eth0/eth5 两个网卡，后来通过ifconfig -a 发现多了两个__tmpxxx的网卡

ifconfig -a 

__tmp1207132519 Link encap:Ethernet  HWaddr E4:1F:13:F7:73:62

经查询，这是一个bug，原因是MAC地址没有在配置文件中

DEVICE=eth0
BOOTPROTO=none
E4:1F:13:F7:73:62
ONBOOT=yes
MASTER=bond0
SLAVE=yes

添加如下：

HWADDR=00:1B:21:B4:60:F2
