If an application is calling rdma_resolve_ip() and a status of -ENODATA is returned from addr_resolve_local/remote(), the timeout mechanism waits until the application's timeout occurs before rechecking the address resolution status; the application will wait until it's full timeout occurs. This case is seen when the work thread call to process_req() is made before the arp packet is processed.
I don't understand the issue. process_req() is invoked whenever a network event occurs, which rechecks all pending requests.
This patch is in addition to Steve Wise's neigh_event_send patch to initiate neighbour discovery sent on 9/12/2007.
This patch looks unrelated to Steve's patch. Can you clarify the relationship?
