I am not quite sure I follow you here, but I think it is not enough that
lookup succeeds, you need to synchronize between the removal cb and the
verbs calls, via locking mechanism of some sort (lock before device free
and lock before calling ib_query_port, for example)
I don't think that the CMA needs to register as a device client. I was
referring to providing a call such as:
ib_device_get_ip(struct ib_device, struct sockaddr*, int num_sockaddr);
To return all IP addresses associated with the given device. The caller can now
coordinate calling this routine with device removal.
