net: ipv6: Set protocol to kernel for local routes
IPv6 stack does not set the protocol for local routes, so those routes show up with proto "none": $ ip -6 ro ls table local local ::1 dev lo proto none metric 0 pref medium local 2100:3:: dev lo proto none metric 0 pref medium local 2100:3::4 dev lo proto none metric 0 pref medium local fe80:: dev lo proto none metric 0 pref medium ... Set rt6i_protocol to RTPROT_KERNEL for consistency with IPv4. Now routes show up with proto "kernel": $ ip -6 ro ls table local local ::1 dev lo proto kernel metric 0 pref medium local 2100:3:: dev lo proto kernel metric 0 pref medium local 2100:3::4 dev lo proto kernel metric 0 pref medium local fe80:: dev lo proto kernel metric 0 pref medium ...
