The patch handles this by routing the communication establish event directly to the IB CM for processing, which will force the connection in the established state and generate a connection event to the user. The requirement for RDMA CM users is that they must wait for an RDMA_CM_EVENT_ESTABLISHED event before posting sends. Are we happy with this requirement? The effect on the user is that either the receive processing must be deferred or sends must be queued until such an event occurs. The alternative is to add an rdma_establish() call that a user may call after polling their first receive completion. - 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
