What is this trying to do anyhow? If the addr has truely changed why
does the bind fail?

When the active physical link member of bonding interface in active-standby
mode gets faulty, the standby link will represent the assigned addresses on
behalf of the active link.
Therefore, RDMA communication manager will notify iSER target with
RDMA_CM_EVENT_ADDR_CHANGE.

Ah, here is my recollection...

However I think that if we move that into a work, we should do it
periodically until we succeed or until the endpoint is torn down so
we can handle address removed and restore use-cases.

See nvmet-rdma for an example of what I'm talking about.
