Show the current configuration of the network, for example:
Two forms of the <code>ifconfig</code>command are supported:
</p>
<ul><pre>
<ol>
<li>
<p>
With one or no arguments, <code>ifconfig</code> will shows the
current configuration of the network and, perhaps, the status of ethernet
device:
</p>
<ul><pre>
ifconfig
ifconfig [nic_name]
</pre></ul>
<p>
As an example:
</p>
<ul><pre>
nsh&gt; ifconfig
eth0 HWaddr 00:18:11:80:10:06
IPaddr:10.0.0.2 DRaddr:10.0.0.1 Mask:255.255.255.0
</pre></ul>
<p>
if uIP statistics are enabled (<code>CONFIG_NET_STATISTICS</code>), then
this command will also show the detailed state of uIP.

If both the network interface name and an IP address are supplied as arguments,
