net/openospfd is also affected. Attached is the simple patch to take
into account the withdrawal of RTF_LLINFO. Perhaps something else
should be done -- I'll up some -CURRENT systems and will try to test the
Real Stuff (TM).

Subject: [PATCH] Fix usage of RTF_LLINFO due to the ARP-v2 changes
ARP-v2, commited in SVN rev 186119, eliminated RTF_WASCLONE,
RTF_CLONING and RTF_LLINFO,
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/net/route.h?rev=3D1.77
The latter flag was used in OpenOSPFD to skip ARP entries from the
routing table. We're just conditionalizing the code on the existence of
RTF_LLINFO variable. Perhaps checking __FreeBSD__ value will be better:
errors due to the non-included net/route.h won't be spotted in the
former case. But since many RTF_* constants are used in kroute.c, this
shouldn't be a problem, at least now.
