[ofa-general] [PATCH] CMA: Enable conn_id remove

[Vladimir Sokolovsky]

Hi Sean,
I have the following issue: The IB driver can't be unloaded after running applications over RDS.
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.
