IIRC, that's what I found after divig the code. It's an issue reported/fixed by Finn. I also don't have the nic for testing. [Finn] Yes, this was needed to make our test setup using an XL710 work, with the rte_flow implementation. It's a while ago so I don't exactly remember how we ended up with this solution. However, we are definitely not Intel XL710 experts, so there might be other ways to achieve the rte_flow functionality. This issue, and problem raised about the overall change in configuration impact on NICs using this setting (Napatech does not use it), I think should be reviewed/verified by NIC vendors using it. --yliu _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
