phantun_client missed ipv6 addr on tun0

[a0s]

Looks like a bug:

> phantun_client --help
--tun-local6 <IP>                [default: fcc8::1]
--tun-peer6 <IP>                 [default: fcc8::2]

> phantun_server --help
--tun-local6 <IP>                [default: fcc9::1]
--tun-peer6 <IP>                 [default: fcc9::2]

When i start

RUST_LOG=trace phantun_client \
--local 104.248.91.157:1111 \
--remote 157.245.78.39:2222 \
--tun-local 192.168.200.1 \
--tun-peer 192.168.200.2 \
--tun-local6 fcc8::1 \
--tun-peer6 fcc8::2 \
--tun tun0

> ip a show tun0
tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen
 500
    link/none
    inet 192.168.200.1 peer 192.168.200.2/32 scope global tun0
       valid_lft forever preferred_lft forever
    inet6 fe80::d76c:d7f7:698d:4e6f/64 scope link stable-privacy
       valid_lft forever preferred_lft forever
>>>WHERE IS MY fcc8::* ?!?<<<

But phantun_server works as it should:

RUST_LOG=trace phantun_server --local 2222 --remote 127.0.0.1:51820 --tun-local 192.168.201.1 --tun-peer 192.168.201.2 --tun-local6 fcc9::1 --tun-peer6 fcc9::2 --tun tun0

>ip a show tun0
17: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 500
    link/none
    inet 192.168.201.1 peer 192.168.201.2/32 scope global tun0
       valid_lft forever preferred_lft forever
    inet6 fcc9::1 peer fcc9::2/128 scope global                  <<<=== OK, ITS HERE
       valid_lft forever preferred_lft forever
    inet6 fe80::cc20:2f04:1a29:51f2/64 scope link stable-privacy
