[openib-general] re cma upcalls serialization / disconnected event question

[Or Gerlitz]

Hi Sean,

Can a ULP assume that cma callbacks for to the same CMA ID 
are serialized? 

Also and related to this, is it correct that ***always** before 
DISCONNECTED event there will be one of {ESTABLISHED, REJECTED, 
CONNECT_ERROR}?

I am talking on the active side and assuming there's no notification
on CONNECT_RESPONSE.

thanks,

Or.
