Thanks for the reply, @networkplumber :) No KNI interface here, unfortunately. Just a plain-ol DPDK ethernet device.
In the scenario where the RETA size is 0 I'm using the vmxnet3_pmd. Within the application the eth devices are initialized and I make a call to rte_eth_dev_info_get(). What is everyone else seeing for the RETA size using vmxnet3?
