Subject: Re: [ofa-general] [PATCH] RDMA/CMA: Implement rdma_resolve_ip retry
 enhancement.

> 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?
