Is there support for IPv6 in MyCloud Gen2?

In network setting in Web UI I have manually set up IPv6 DNS server address. Now there appeared address in the IPv6 field, but only link local one (fe80::…).

$ ip addr show dev egiga0

2: egiga0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP qlen 532
link/ether 00:90:a9:ed:5c:49 brd ff:ff:ff:ff:ff:ff
inet 192.168.10.9/24 brd 192.168.10.255 scope global egiga0
valid_lft forever preferred_lft forever

The issue seems to be lack of kernel support for this protocol.
$ ping6 ipv6.google.com

PING ipv6.google.com (2a00:1450:401b:803::200e): 56 data bytes
ping6: can’t create raw socket: Address family not supported by protocol

Is there any support for IPv6 in this device?
