Below are the system details under which the sample= application (L2 Forward) is being run. Platform: Linux 2.6.32-358.17.1.el6.x86_64 VMWare: ESXI 5.1 Driver: vmxnet3-usermap L2 FWD program is being run with a load of ~100K packets per second on RX q= ueue. The sample application successfully forwards the packets to other end= for some time. However, after around 1 hour run, I see that rte_eth_rx_bur= st returns 0 packets received, though the load generator continuously sends= packet to the L2 FWD program. The statistics reported by the sample application also shows the "Packets r= eceived:" value stops incrementing. I also used "rte_eth_stats_get" api to check if any packets are being recei= ved on the interface. This api shows the packets are being received at the = interface, however rte_eth_rx_burst does not pick these packets. Can you please help me as to why this behavior is seen. Also, please let me= know if you need further details. Thanks ~Neeraj
