create a workable IPv6 network for ocserv clients

1. enable NDP proxy at ocserv server host: sysctl -w net.ipv6.conf.all.proxy_ndp=1 .

2. assign a sub network of ocserv server host IPv6 network for clients, for example:

   if the IPv6 address of ocserv server host inteface eth0 is 2608:8207:7888:a450::1/64, then add the fellowing lines into ocserv.conf:

   ipv6-network = 2608:8207:7888:a450:cafe::/80
