The flag is not needed. It is only possible to retrieve arp entries by

the entries in the routing table and look at each one to determine
which are cloned routes (dynamic host routes) which contain ARP
entries.
Does this mean that the snmp daemon cannot monitor the arp entries
through the routing socket anymore? This would be a performance issue,
since it would have to fetch the ARP table from the kernel each time it
is asked for. Now it refreshes the table only if it is older than 30
seconds and in the mean time monitors routing messages.
this is one of the things that worried me abuot the arp change, which
is is that the change itself is fine but that I had no idea if LLINFO
was BSD specific or if other ports and 3rd party code would rely on
the connection between routing and ARP.
maybe ARP activity should produce routing socket events.
and maybe teh output should synthesize the missing entries.

The code in question on the Wine side is
#if defined(HAVE_SYS_SYSCTL_H) && defined(NET_RT_DUMP)
int mib[] = {CTL_NET, PF_ROUTE, 0, AF_INET, NET_RT_FLAGS, RTF_LLINFO};
and there is nothing FreeBSD-specific in dlls/iphlpapi/ipstats.c as far
as I can see.
If the arp-v2 update now made us incompatible both with earlier versions
of FreeBSD and Linux, that sounds like something that should be fixed
(instead of hacking applications like Wine).
On the other hand, the commit message at
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/net/route.h
explicitly says
The change in design obsoletes the semantics of RTF_CLONING,
RTF_WASCLONE and RTF_LLINFO routing flags. The userland applications
such as "arp" and "ndp" have been modified to reflect those changes.
so I guess it's not so easy.
How many other ports are affected?
What shall we do on the Wine front? Simply #ifdef-ing out the code in
question may not be the best of ideas, either. :-(
