I believe he's trying to control the IB MTU, not the IP MTU. The IB MTU can be restricted based on the HCA capabilities or the switch capabilities that the HCA may be connected to. Do you know if these support a larger MTU size? - Sean _______________________________________________ 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
