One side effect of the TSO changes is that one extra descriptor will be used for outgoing packets. This is because we have to put the headers as well as the user data, into page based buffers now. Perhaps you can experiment with increasing the transmit descriptor table size, if that's possible. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
