Description
Currently, the ndp daemon runs in an NGZ even if there is only a loopback IPv6 address present.
root@hawkeye:~# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
net0/_a from-gz ok 10.0.0.86/26
lo0/v6 static ok ::1/128
root@hawkeye:~# ps -ef | grep ndpd
root 4960 4302 0 Jan 22 ? 0:00 /usr/lib/inet/in.ndpd
If loopback is the only IPv6 address present, ndpd does not need to run.

Testing notes:
After the change, the zone does not have in.ndpd running unless there is a non-loopback IPV6 address configured, for example:
root@test:~# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
test0/_a from-gz ok 172.27.10.100/24
lo0/v6 static ok ::1/128
root@test:~# ps -ef | grep ndp
root@test:~# ipadm create-addr -t -T addrconf test1/v6local
root@test:~# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
test0/_a from-gz ok 172.27.10.100/24
lo0/v6 static ok ::1/128
test1/v6local addrconf ok fe80::8:20ff:fe5c:6ec0/10
root@test:~# svcadm restart routing-setup
root@test:~# ps -ef | grep ndp
