The feature was dropped during the ARP code rewrite because it was considered
obscure enough to not warrant the special case code it needs. Back
then nobody complained so it was dropped.
Maybe the users should participate more in the development cycle...Now it is
too late. If someone wants it seriously he should contribute a patch.
