MPD 是什么，它的官方主页上是这么说的：

MPD is a multi-link PPP daemon for FreeBSD based on netgraph(4). It is designed to be both fast and flexible. It handles configuration and negotiation in user land, while routing all data packets strictly in the kernel. It supports several of the numerous PPP sub-protocols and extensions

但由于是“based on netgraph”，因此，需要修改一下内核配置文件，加入：

options         NETGRAPH 
options         NETGRAPH_ETHER 
options         NETGRAPH_SOCKET 
options         NETGRAPH_PPPOE

System: FreeBSD-5.4_stable i386
