[quagga-dev 4150] OSPFD and MTU Mismatch

Am I right in thinking that there is no way to persuade OSPFD to disable
OSPF MTU mismatch detection on received DBD packets between neighbours
(see code snippit below from ospf_packet.c):
/* Check MTU. */
if (ntohs (dd->mtu) > oi->ifp->mtu)
zlog_warn ("Packet[DD]: Neighbor %s MTU %u is larger than [%s]'s
inet_ntoa (nbr->router_id), ntohs (dd->mtu),
IF_NAME (oi), oi->ifp->mtu);
Am I missing something or is there no way of doing the equivalent (in
cisco terms) of:
ip ospf mtu-ignore
If there is not another way of achieving this, do you think an
implementation similar to Cisco's is worthwhile, or is it too much of a
bodge for the RFC purists ?
