stable inclusion from linux-4.19.171 commit 47d6a700430234cb0328722833ac3a0788ea7f38
--------------------------------
commit ceed9038b2783d14e0422bdc6fd04f70580efb4c upstream.
The multicast route ff00::/8 is created with type RTN_UNICAST:
$ ip -6 -d route unicast ::1 dev lo proto kernel scope global metric 256 pref medium unicast fe80::/64 dev eth0 proto kernel scope global metric 256 pref medium unicast ff00::/8 dev eth0 proto kernel scope global metric 256 pref medium
Set the type to RTN_MULTICAST which is more appropriate.
