net/ipv6: use configured metric when add peer route
[ Upstream commit 07758eb9ff52794fba15d03aa88d92dbd1b7d125 ]
When we add peer address with metric configured, IPv4 could set the dest
metric correctly, but IPv6 do not. e.g.
]# ip addr add 192.0.2.1 peer 192.0.2.2/32 dev eth1 metric 20
]# ip route show dev eth1
192.0.2.2 proto kernel scope link src 192.0.2.1 metric 20
]# ip addr add 2001:db8::1 peer 2001:db8::2/128 dev eth1 metric 20
]# ip -6 route show dev eth1
2001:db8::1 proto kernel metric 20 pref medium
2001:db8::2 proto kernel metric 256 pref medium
Fix this by using configured metric instead of default one.
