I also = saw another thread > discussing better device capability APIs and hopefully this will not be n= eeded then. somehow hijack this thread, in my company ESXi environment, we are using tagged vlan in ESXi (select "network label" in vsphpere client when adding VM network adapter. I found the DPDK application packet running on one ESXi VM can't reach to other ESXi VM, is this because VLAN offload not implemented in vmxnet3 PMD ? any clue can I address the tagged vlan in ESXi environment?
