testsuit与自己编译的内核比较 一点问题

以下是自己编译的uClinux内核在skyeye上运行时输出的信息：

自己编译的uClinux ping主机不通，主机ping的通test里的都ping的通
比较后发现自己编译的输出中少了Command: /bin/ifconfig eth0 up 10.0.0.2这一句，那问题应该是虚拟出的eth0没有up   

问题是不是出在内核编译的选项上？因为我都是用的test中的skyeye.conf输出中还有些地方不一样 也不太理解
自己也在做一个协议方面的项目 了解到有skyeye这样一个环境 非常高兴 希望能通过skyeye实现一个调试的环境
困扰几天了 望高人解答

1. 你的uClinux需要加入rt8019的驱动程序，才可以和 skyeye中的模拟网卡配合使用。你可以参考 wiki上的一篇文档：
http://skyeye.wiki.sourceforge.net/uClinux#tocuClinux4

2. ifconfig命令，在testsuite是内核启动之后自动运行的命令，你可以手动的运行
ifconfig eth0 10.0.0.2
这个应该不是问题。

还有用skyeye-1.2.6版本好一点，1.2.7_rc1是个测试版本，还有一些bug

这么快就有了回答 谢谢

回复 2# ksh 的帖子

按照http://skyeye.wiki.sourceforge.net/uClinux#tocuClinux4中所述，在uClinux-dist/linux-2.4.x/driver/net中加入了Rtl8019.c和Rtl8019.h两个文件之后，修改uClinux-dist/linux-2.4.x/driver/net下的Makefile，修改为
ifeq ($(CONFIG_ARCH_ACORN),y)
mod-subdirs   += ../acorn/net
subdir-y      += ../acorn/net
obj-y         += ../acorn/net/acorn-net.o
obj-y         += rtl8019.o（加入的内容）
endif

然后直接make menuconfig,make dep,make
输出信息为：

Makefile修改后，是不是要在编译时选一些选项？
在uClinux下 ifconfig eth0 10.0.0.2和ifconfig eth0 up 10.0.0.2的输出结果不一样（结果如上） 提示的两个错误是什么呢？
