NetworkManager 1.2.2 - IPV6 badly set

[nmset]

Hello,

Since my last upgrade, IPV6 is badly set with NetworkManager 1.2.2, on ODROID-U2 (armv7h).

Result of
$this->bbcode_second_pass_code('', '#LC_ALL=C ping 2a00:1450:401b:800::2003 # a Google valid address
ping: sendmsg: Network is unreachable')

If I downgrade to 1.0.8, normal function is restored, as before the last
update.

My conf file :
$this->bbcode_second_pass_code('', '#cat /etc/NetworkManager/system-connections/eth0

[connection]
id=eth0
uuid=<uuid>
type=ethernet
permissions=
secondaries=

[ethernet]
mac-address=<mac>
mac-address-blacklist=

[ipv4]
address1=192.168.x.xyz/24,192.168.x.1
dns=<dns>;
dns-search=
method=manual

[ipv6]
addr-gen-mode=stable-privacy
address1=<prefix>:<address1>/64 ,<prefix>::1
address2=fd01:2345:6789:a::119/64
address3=fe80::<LL_ADDR_1>/64
dns=2a01:e00::1;2a01:e00::2;
dns-search=
may-fail=false
method=auto')

Here is the result of
$this->bbcode_second_pass_code('', '#ip addr

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group
default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

inet6 fe80::<MAC_DERIVED>/64 scope link

Same results if the ipv6 section is :
$this->bbcode_second_pass_code('', '[ipv6]
addr-gen-mode=stable-privacy
dns-search=
may-fail=false
method=auto')


No stateless autoconfiguration address is assigned in either case. This does
not happen on x86_64 with NetworkManager 1.2.2.

It's probably an upstream problem, I just wish your advice before reporting
there.

Regards.
