I have a basic question. Do you know if multiple TX queues are supported  for vmx + netmap ? Basically I'm using pkt-gen to generate bulk traffic @10Gbps and its OK with packet size >~1000b. For small packets I should use multiple cores/processes to be able to generate the required pps, but pkg-gen complain that I have only one queue. I tried adding multiple queues for vmx on loader.conf (can verify with sysctl) but netmap still complaining there is only one queue. sysctl -a | grep vmx.1: dev.vmx.1.mbuf_load_failed: 0 dev.vmx.1.mgetcl_failed: 0 dev.vmx.1.defrag_failed: 0 dev.vmx.1.defragged: 0 dev.vmx.1.nrxqueues: 8 dev.vmx.1.ntxqueues: 4 dev.vmx.1.max_nrxqueues: 8 dev.vmx.1.max_ntxqueues: 4 dev.vmx.1.%parent: pci4 dev.vmx.1.%pnpinfo: vendor=0x15ad device=0x07b0 subvendor=0x15ad subdevice=0x07b0 class=0x020000 dev.vmx.1.%location: slot=0 function=0 dbsf=pci0:11:0:0 handle=\_SB_.PCI0.PE50.S1F0 dev.vmx.1.%driver: vmx dev.vmx.1.%desc: VMware VMXNET3 Ethernet Adapter pkg-gen still saying one queue for vmx: Sending on netmap:vmx1: 1 queues, 2 threads and 4 cpus. Thanks in advance. Santiago
