Hi all We are trying to test multiple RX queues with sample program xdpsock from kernel on vmware virtual machine with 2 queues. The driver on the NIC is: # ethtool -i ens192 driver: vmxnet3 version: 1.4.16.0-k-NAPI NIC has 2 queues, I can check it by ethtool -S. But when I try to use queue 1, I am getting following: # ./xdpsock -i ens192 -q 1 /home/jmilan/ws/pt-xdp/linux/samples/bpf/xdpsock_user.c:xsk_configure_socket:315: errno: 1/"Operation not permitted" Any ideas what the problem could be? Maybe vmxnet3 driver does not support some necessary operations related to queues? Best Regards Július
