I am testing an l2fwd use-case. I am executing the use-case with two CPUs & two interfaces. One interface with 2 Rx queues receives pkts using 2 threads with 2 associated CPUs. Both the threads can forward the packet over the 2nd interface which also has 2 Tx queues mapped to 2 CPUs. I am sending packets from an external packet generator and confirmed that both queues are receiving packets. *When I run odp_pktin_recv() on both the queues, the packet* * forwarding works fine. But if I put a sleep() or add a busy loop instead of odp_pktin_recv() * *on one thread, then the other thread stops receiving packets. If I replace the sleep with odp_pktin_recv(), both the queues start receiving packets again. *I encountered this problem on the DPDK pktio support on ODP 1.16 and ODP 1.17. On socket-mmap it works fine. Is it expected behavior or a potential bug?
