net: ipv6: Use compressed IPv6 addresses showing route replace error

David Ahern · davem330 · commit 7d4d5065ecb0 · 2017-02-04T19:58:14.000-05:00
ip6_print_replace_route_err logs an error if a route replace fails with
IPv6 addresses in the full format. e.g,:

IPv6: IPV6: multipath route replace failed (check consistency of installed routes): 2001:0db8:0200:0000:0000:0000:0000:0000 nexthop 2001:0db8:0001:0000:0000:0000:0000:0016 ifi 0

Change the message to dump the addresses in the compressed format.
