python解析ifconfig 输出成字典

有个需求需要将ifcofig输出解析出来，这里将写的整理出来。方便后续使用。

eth0      Link encap:Ethernet  HWaddr 00:50:53:b2:23:e6
          inet addr:10.190.179.83  Bcast:10.180.255.255  Mask:255.255.0.0
          inet6 addr: fe80::250:56ff:feb2:33e5/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:28559410 errors:0 dropped:48189 overruns:0 frame:0
          TX packets:2392292 errors:0 dropped:0 overruns:0 carrier:0

示例输出
