8260目标板，配置了两个eth口。
在config.h和configNet.h中已经把两个eth口打开。
问题是：
目标板引导成功VxWorks以后，板上的eth口只能使用一个。（可能是因为我在config.h中只配置了一个目标板地址？怎样配置多个呢？我的配置是：
#define DEFAULT_BOOT_LINE BOOT_DEV_NAME "(0,0)host:vxworks " "e=192.168.2.254 " "h=192.168.2.65 " "u=anonymous pw=user " "f=0x80 tn=mpc8260"）
但是板上的eth口与网络连接后，显示灯能够正常亮，应该说明物理链路已经建立成功。
在VxWorks的shell下希望配置出另外一个ip地址。
曾经尝试过的命令：ipAttach( ), ifMaskSet( ) ，ifAddrSet( ), and hostAdd( )
但是ifAddrSet()的返回值是－1，不能成功。
哪位高手帮忙提示一下？
多谢。
谢谢版主gem2000
不过在
“然后修改sysLib.c，定义第二个网口的mac地址以及获得mac地址的函数”
上能否多给些提示。
我把原先我设置的方法和具体输出贴出来，gem2000帮忙看一下。
