How do you know that the old path is back ? Do you have a notification
handler called, or you need to query periodically ?

Thanks.

Yes.

The ib_cm does not perform any QP state transitions.  That is left up to
the user, since the CM is unaware of other actions related to the QP
that the user may be performing.
