Is the connection manager api considered 'stable' yet? Last I knew it was still undergoing a lot of development. Wouldn't it be possible to adapt the existing tcp connection setup code to work for Iwarp without using the connection manager? Most of the time when I test IB networks, I just bind to ethernet eth0 interfaces anyway. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
