net/ipv6: use configured metric when add peer route
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.
