I have a 4 port aggr that has 4 VLAN's running over it.

untagged = vlan 30 (because smartos admin nic wants this)
tagged = vlan 10, vlan 20, vlan30, vlan40

trunk0/v6auto = ipadm create-addr -t -T addrconf trunk0/v6auto

expected result: slaac ip address with label turnk0/v6auto going untagged over trunk0
AKA: 2001:6f8:1480:30:225:90ff:fef1:5506 (correctly setup right after adding -T addrconf)
[root@core ~]# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
trunk0/_a static ok 172.16.30.91/24
lo0/v6 static ok ::1/128
trunk0/v6auto addrconf ok fe80::225:90ff:fef1:5506/10
trunk0/v6static static ok 2001:6f8:1480:30::91/64
trunk0/v6auto addrconf ok 2001:6f8:1480:30:225:90ff:fef1:5506/64

result: all is as it should be, after a minute give or take in.ndpd binds more IP's, one for each VLAN!
