net/ipv6: remove the old peer route if change it to a new one
[ Upstream commit d0098e4c6b83e502cc1cd96d67ca86bc79a6c559 ]
When we modify the peer route and changed it to a new one, we should
remove the old route first. Before the fix:
+ ip addr add dev dummy1 2001:db8::1 peer 2001:db8::2
+ ip -6 route show dev dummy1
2001:db8::1 proto kernel metric 256 pref medium
2001:db8::2 proto kernel metric 256 pref medium
+ ip addr change dev dummy1 2001:db8::1 peer 2001:db8::3
+ ip -6 route show dev dummy1
2001:db8::1 proto kernel metric 256 pref medium
2001:db8::2 proto kernel metric 256 pref medium
After the fix:
+ ip addr change dev dummy1 2001:db8::1 peer 2001:db8::3
+ ip -6 route show dev dummy1
2001:db8::1 proto kernel metric 256 pref medium
2001:db8::3 proto kernel metric 256 pref medium
This patch depend on the previous patch "net/ipv6: need update peer route
when modify metric" to update new peer route after delete old one.
