>Description:
If I use the following procedure, it doesn't properly delete IPv6 addresses tied to an interface...

1. Configure an address in /etc/rc.conf, e.g.:

ifconfig_em1_ipv6="inet6 3ffe:501:ffff:100::2 prefixlen 64

2. Run service netif restart em1.
3. Verify address via ifconfig em1 | 3ffe:501:ffff:100::2 .
4. Comment out the ifconfig_* line above.
5. Run service netif restart em1 again.
6. Verify that the address has been deleted from the interface via ifconfig em1 | 3ffe:501:ffff:100::2 .
