    IB/addr: Fix IPv6 routing lookup
    
    Include link scope as part of address resolution.  Combine local
    and remote address resolution into a single, simpler code path.
    Fix error checking in the IPv6 routing lookups.
    
    Based on work from:
    David Wilder <dwilder-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>
    Jason Gunthorpe <jgunthorpe-ePGOBjL8dl3ta4EC/59zMFaTQe2KTcn/@public.gmane.org>

Before the change, they were
-#if defined(CONFIG_IPV6) || defined(CONFIG_IPV6_MODULE)

Good catch.  Submit a patch and Cc lkml.

Thanks,
Jon
