Well, first of all, there is no reason we can't provide a mechanism by which the driver can request and obtain a FIB dump. And it can be designed in a way to be preemptible or at least not require RTNL to be held during the entire operation. Sequence counters or similar can be used to make sure that if the table changes mid-dump due to RTNL being dropped, the dump can be rewound and restarted.
