As a rough estimate, Q1, though I will try to get to it after adding support for 
SA events, which likely would be near late November, early December.  The 
framework in the ib_cm is there; I just need a way to signal that failover has 
occurred.

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.
