* Some issues:
*
* 1. libwinet_dump_ipv6_route_table
*
* Before Windows Vista, we have to use command "netsh" to get ipv6
* route table. But the output misses the value of route protocol.
*
* 2. libwinet_edit_route_entry
*
* What should be the value of protocol? MIB_IPPROTO_NETMGMT or
* RTPROT_BABEL_LOCAL
