在QNX下怎样取得MAC地址？
nicinfo
这个命令，我在QNX6.2.1和QNX6.3.2试了，都不能得到网卡的MAC地址！它输出的内容如下：
3COM (90xB) 10BASE-T/100BASE-TX Ethernet Controller

你的MAC地址不是显示在那么？
000102 BE3A28
喔！
但是我的在另一台机子上，却显示如下信息：
INTEL 82557 Ethernet Controller

Current Physical Node ID…FFFFFF FFFFFF

Maximum Transmittable data Unit…1514

Promisuous Mode…Off

get states: Input/Output error
这是为什么？
我的网卡是集成的RTL8169，是945主板上的。我也试过用rtl驱动，命令如下：
“io-net -d rtl vid=0x10ec,did=0x8167 verbose -ptcpip”
但是，提示说没有devn-rtl驱动，将rtl换成speedo，也就是：
“io-net -d speedo vid=0x10ec,did=0x8167 verbose -ptcpip”
这样就没有问题了，在Photon中打开network的配置窗口也可以看到有了device，命令行输入ifconfig也可以看到有了en0这个设备。但是奇怪的很，用nicinfo这个命令时，显示说这块网卡是Intel的，而用pci命令时却说是RealTek的。而且在使用nicinfo时，显示不出网卡的MAC地址。可能还是驱动有问题，但是到底应该怎么写这个装入驱动的命令，我倒迷糊了！
另外，还有就是命令写成这个样子：
“io-net -d rtl verbose -ptcpip”
就不会报错，但是Photon中的network配置不会出现device，ifconfig也不会出现en0这个设备。
devn-xxxxx.so 是网卡驱动。不同的网卡要用不同的驱动。你的是RTL的网卡，但你去用devn-speedo.so，那是不会成功的。
“io-net -d rtl vid=0x10ec,did=0x8167 verbose -ptcpip” – 你能肯定这个命令的提示是“没有devn-rtl驱动”吗？因为你的机器上肯定是有rtl驱动的，你的另一个帖子说“io-net -d rtl -p tcpip” 没有出错，说明你至少是有rtl驱动的。（通常这个文件在/lib/dll/devn-rtl.so）
另外，你同时提到了6.21和6.3.2，到底你是用的哪一个版本？6.2.1是非常旧的版本，而6.3.2只能在安装6.3.0以后才能升级到的。
是这个样子的，我这里有四台机子装了QNX，有两台由于配置了独立网卡，可以正常使用，一台是QNX6.3.2，另一台QNX6.2.1。有问题的是另外两台集成网卡的机子，也是一个是6.3.2，一个是6.2.1，都是945的主板，集成RTL8169网卡。这两台出现问题的现象是完全一样的，没有任何差别。
我也知道devn-speedo是Intel的驱动，realtek的网卡应用devn-rtl，但是我用了两次都出现问题：
第一次“io-net -d rtl vid=0x10ec,did=0x8167 verbose -ptcpip”，报错说没有devn-rtl驱动。
第二次“io-net -d rtl verbose -ptcpip”不报错，但是PHOTON下的network配置中没有device，用ifconfig也没有en0这个设备。
但是，我给它装devn-speedo，它就假假地能出来，但是却用不了。是不是这个驱动具有虚拟网卡的功能啊？ 
我这里的QNX6.3.2不是从6.3.0升级过来的，我这个版本来自我们的供应商，可能他们已经做过处理了吧！
难道集成网卡RTL8169不能用吗？
我觉得你可能把 vid, did 搞错了。

verbose 和 前面的7之间应该有逗号，不能有空格。
io-net -d rtl vid=0x10ec,did=0x8167,verbose -p tcpip
不是。它能“找到设备”，是因为你强行指定了设备号的关系。
我试了一下，加逗号和不加逗号没有什么区别，都说没有devn-rtl驱动
我看了一下devn-rtl.so的驱动说明，其中它的Description写道：
“The devn-rtl.so driver controls Realtek 8139 PCI cards.”
是不是这个驱动它还只能支持RTL8139，还不能支持RTL8169啊？
看看去RealTek的网站看了一下，他们支持RTL8139的驱动是03年开发的，http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=2&PNid=6&PFid=6&Level=5&Conn=4&DownTypeID=3&GetDown=false#RTL8100B(L)/RTL8100C(L)/RTL8101L/RTL8139C(L)
RTL8139C(L)+/RTL8139D(L)/RTL8100(L)
RTL8130/RTL8139B(L)而关于RTL8169他们网站上压根就没有

RTL8169
今天去QNX的网站看了一下，他们的硬件支持列表中也只有RTL8139和8029，没有对RTL的支持。上次那位搞定这块卡的仁兄，是不是没有做完？
唉，这个故事告诉我们：不要盲目相信任何成功案例！
同时对QNX，我在这里要表示最最强烈的不满：为什么应用如此普及的集成网卡就不支持一下？！
