We do not support SIOCGIFADDR for IPv6 because in6_addr is too big.:-p
Use rtnetlink(7) to get ipv6 addresses.
You probably want to use getifaddrs(3) in USAGI package to get 
addresses (H/W addresses, ipv4 addresses and ipv6 addresses) on interfaces.
The interface was originally from BSDI and also available on 
KAME(BSD)-based OS's.
