That's bad. Did you check if the send is failing due to overrunning the send queue? > (I suspect, but haven't verified, that the difference is due to > the sharing of ipoib_dev_priv's tx_outstanding member between > the UD and CM IPoIB QPs, the value of tx_outstanding is used > to determine when to call netif_stop_queue().) A while ago, I was worried about the handling of tx_outstanding and how the driver makes sure that it doesn't post too many sends, but I managed to convince myself that the code was OK. Guess we should check it over one more time. - 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
