When using the ping-pong application or the pkt-gen application, the sender is able to transmit packets but, at the receiver side on call to rte_eth_rx_burst it get's stuck as it returns a value of 0 every time in the poller body function. As a result it is not able to flush the packet to the rx-queue which is used by the UDPDK recvfrom to retrieve the packets. I have confirmed that the packet is reached at the receiver side using rte_eth_stats_get() method but not sure why rte_eth_rx_burst is not able to retrieve the packets?
