Is there a limitation on the number of num-tx-queues and num-rx-queues we can associate with vmxnet3? I have 12 worker threads running but when i try to associate more than 4 num-rx-queues i get error saying "vmxnet3 failed to activate dev error 1" .... *Setup Details:* I have vpp running on 16 vCPUs and set the worker thread to use vCPU (2-15) i.e 14 worker threads. * Error:* I run into vmxnet3 error when i try to create vmxnet interface with: * num-tx-queue set to greater than 8 (Error #1 below) * num-rx-queues set to greater than 4 (Error #2 below) ERROR #1: vCPUs = 16 and Worker Threads = 14 vpp# create interface vmxnet3 0000:13:00.0 rx-queue-size 2048 tx-queue-size 2048 num-tx-queues 12 num-rx-queues 4 bind ERROR: create interface vmxnet3: number of tx queues must be <= 8 and <= number of CPU's assigned to VPP Works fine when num-tx-queues 8 ERROR #2: vpp# create interface vmxnet3 0000:13:00.0 rx-queue-size 2048 tx-queue-size 2048 num-tx-queues 8 num-rx-queues 5 bind ERROR: create interface vmxnet3: error on activating device rc (1) Works fine when num-rx-queues 4 vpp# create interface vmxnet3 0000:13:00.0 rx-queue-size 2048 tx-queue-size 2048 num-tx-queues 8 num-rx-queues 4 bind *vpp# sh int rx-placement* Thread 1 (vpp_wk_0): node vmxnet3-input: vmxnet3-0/13/0/0 queue 0 (polling) Thread 2 (vpp_wk_1): node vmxnet3-input: vmxnet3-0/13/0/0 queue 1 (polling) Thread 3 (vpp_wk_2): node vmxnet3-input: vmxnet3-0/13/0/0 queue 2 (polling) Thread 4 (vpp_wk_3): node vmxnet3-input: vmxnet3-0/13/0/0 queue 3 (polling) *Reference:* https://vpp.flirble.org/master/db/df1/clicmd_src_plugins_vmxnet3.html create interface vmxnet3 <pci-address> [rx-queue-size <size>] [tx-queue-size <size>] [num-tx-queues <number>] [num-rx-queues <number>] [bind] [gso].
