Re: [PATCH] ipv6: socket SO_BINDTODEVICE lookup routing fail without IPv6 rule.

     When using socket IPv6 with SO_BINDTODEVICE, if IPv6 rule is not
        matched, it will return ENETUNREACH. In fact, IPv4 does not behave
        this way. IPv4 prioritizes looking up IP rules for routing and
        forwarding, if not matched it will use socket-bound out interface
        to send packets. The modification here is to make IPv6 behave the
        same as IPv4. If IP rule is not found, it will also use
        socket-bound out interface to send packts.

Please create test cases for IPv4 and IPv6 showing the problem - what
you are configuring and the expected result.
