I have the following issue: The IB driver can't be unloaded after running

Do you mean the HCA driver? Are there still active connections when the driver

Yes, HCA driver and there are active connections when the driver is unloaded.

I saw that the 'dev_remove' counter does not reach 0 value on the passive side
(after connection establishment).
Please review the following patch:
CMA: Enable conn_id remove on the passive side after
connection establishment.

This looks correct to me, but I'd like to understand why we don't see problems
more often.
