[dpdk-dev] RSS, performance, and stability issues vmxnet3-pmd

I?m unable to get RSS to work properly with vmxnet3-pmd. The first issue is that the number of rxqs must be power of 2. Otherwise, rte_eth_dev_start() fails due to inability to activate vmxnet3 NIC. This is not too big of a deal, but physical NICs don?t have this requirement. The second issue
