Not sure what you mean about a performance problem... if you're talking about the mthca/mlx4 internals, then we just need a private P_Key/GID cache inside the driver. This can be updated synchronously when processing MADs, rather than having all the complicated logic in the current caching module. But I don't think sending MADs is really a fast path anyway. - 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
