Hi Neeraj, I am glad your usecase works.
Please do let me know what is the maximum throughput you are able to achieve with vmxnet3 (assuming your underlying physical NIC is 10 Gig), it will be interesting to see the performance.

Few packet buffers were not being freed which lead to slow leak of mbufs. ~Neeraj -----Original Message----- From: dev [mailto:dev-boun...@dpdk.org] On Behalf Of ext Jain, Neeraj 3.

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 queue. 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_burst 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 received:" value stops incrementing. I also used "rte_eth_stats_get" api to check if any packets are being received 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.
