[OpenIndiana-discuss] IPv6 network error

[russell]

Hi

On Sunday evening I started to get the following messages after 
installing a pfsense firewall

May 18 22:33:06 tesla in.ndpd[972]: [ID 294872 daemon.error]

prefix_update_k: SIOCLIFADDIF (prefix  if e1000g0): Result too large

when I use "ipadm show-if"

IFNAME     STATE    CURRENT      PERSISTENT
lo0        ok       -m-v------46 ---
e1000g0    ok       bm--------46 -46
e1000g1    down     bm--------46 -46

and with "ipadm show-addr"

ADDROBJ           TYPE     STATE        ADDR
lo0/v4            static   ok           127.0.0.1/8
e1000g0/v4        static   ok           172.16.26.110/24
lo0/v6            static   ok           ::1/128
e1000g0/v6        addrconf ok fe80::215:17ff:fe91:7e46/10
e1000g0/v6l       static   ok fd22:d18a:1556:1:6723:1023:d1cc:1355/64
e1000g0/v6g       static   ok 2a02:8010:d00d:1:215:17ff:fe91:7e46/64
e1000g0/?         addrconf down 2a02:8010:d00d:1:215:17ff:fe91:7e46/64 
(this line repeated 252 times)

Can any suggest what I need to change to get rid of the ndpd messages 
and the e1000g0/?  addresses

TIA
