This is my current preferred solution.

I don't have an issue with the rdma_cm issuing some sort of notification event
when an IP address mapping changes.  I would use an event name that indicated
this, rather than 'disconnect'.

If this is implemented, I'd like to minimize the overhead per rdma_cm_id
required to report this event.
