Hi Eduard, Thanks very much for the suggestion, now with "ethernetX.usdpRSS=1"(in vmx file) RSS working well on my guest VM (with vmxnet3 PMD of DPDK-17.11). i'm using ESXi-6.7 update-1, but, by default RSS did not worked. By enabling the above suggested option only, i could see the UDP packets were load-balancing very well on multi-queues.
On top of this, for better performance do we need to enable any more extra flags in "vmx" file ? Thanks, Madhukar.
