As far as I can tell, it doesn't do anything. Flow control is a parameter of the IB CM REQ/REP messages, so are exposed to the user. I don't see how a user can make use of it in any practical way, however. It isn't used to configure anything on the QP from what I can tell. This is why I mentioned that the only use I can think of is for an app to change its algorithms based on whether this value is set or not, but I have a hard time imagining an app doing so. - Sean _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
