The IB spec doesn't allow changing RNR retry on RTS to RTS transitions. Probably because synchronizing the change with in-flight send requests (that might be doing RNR handling at that moment) is too much of a mess. - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
