I have not had the pleasure of testing this specific NIC myself, but from cursory view of kernel sources the message indicate that the driver is attempting an HWRM_CFA_FLOW_ALLOC operation and is getting a HWRM_ERR_CODE_INVALID_PARAMS error. My hunch would be there are some flow attributes in use that the driver/firmware does not support. If this is a 5.4 kernel it might be conntrack, you could try to disable port security for all networks and ports (make sure port-security is enabled in Neutron ML2 though, otherwise you would not be able to disable it properly). -- Frode Nordahl > > -- > Regards, > > > Ammad > _______________________________________________ > discuss mailing list > disc...@openvswitch.org > https://mail.openvswitch.org/mailman/listinfo/ovs-discuss _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
