Looping in the dpdk-ovs list. * Does the new vhost API allow a user to know if all the relevant offloads have been turned on/off for that interface? It seems that this is possible through the virtio_net structure but it would be good to get some feedback from the relevant person working on DPDK (Huawei?). * If this is the case, then it is probably in the realm of the vswitch do the actual checksum (for VM-VM) or correctly configure the NIC when sending out through the physical interface. Comments? Mark
