Recovery from NUD_FAILED state


I have an offload engine, where the engine will add the new IPv6 header, and the user application will try to send the neighbor solicitations and resolve neighbors. Kernel will not send any neighbor requests for this new IPv6 destination address.

When the neighbor is in NUD_FAILED state at that instant, if application sends a neighbour solicitation, then the neighbor advertisement received by peer is not making the neighbor state to get changed (to NUD_REACHABLE).

Is there any way to come out of this situation?
