Each NIC has N ri= ngs. Each LCORE should be handling one RQ of one NIC exactly. So all the LCORE's= on socket 0 should handle RQs from the NIC 0 and LCORE's on socket 1 should handle only RQ's from NIC 1. Similarly for the TX. Each LCO= RE would only handle one and only one RQ. In total there will be 2xN LCORE'= s. Is there a similar model implemented in the dpdk/examples? Are there any ch= allenges implementing such model. Thanks -Anil
