[ Upstream commit c7036d97acd2527cef145b5ef9ad1a37ed21bbe6 ]
A user reported that routes are getting installed with type 0 (RTN_UNSPEC) where before the routes were RTN_UNICAST. One example is from accel-ppp which apparently still uses the ioctl interface and does not set rtmsg_type. Another is the netlink interface where ipv6 does not require rtm_type to be set (v4 does). Prior to the commit in the Fixes tag the ipv6 stack converted type 0 to RTN_UNICAST, so restore that behavior.
