Do you have any evidence that the packets are actually crossing the switch? the way we debug RoCE connectivity issues is configuring port mirroring on the switch and capture the mirrored packets on the host where packets are mirrored, and feed them to wireshark (the official/latest versions support parsing of RoCE/IB packets), on that host you can also observe L2 mac/vlan header of the packets to see if it matches what you expected. But even before that, I would check the switch counters to see the packets aren't dropped. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
