Hi Sean.

I'm validating the values of the CM:REQ packet and i noticed the 
following behavior:
When side A sends a REQ message to side B, the values of several 
attributes are being switched:

for example:
side A puts the following values:
    REQ:initiator_depth           = 1
    REQ:responder_resources = 2
Side B (in the event) get the following values in the CM event (in the 
ib_cm_req_event_param structure)
    REQ:initiator_depth           = 2
    REQ:responder_resources = 1

I see the same behavior for the attributes:   local_cm_response_timeout 
<-->  remote_cm_response_timeout.

Is this is the behavior i should expect from the CM?

thanks
Dotan
