Hi, When calling tcpreplay for any device and not necessarily the kni it can take a few minutes until the packet transmission starts. this occurs only when the kni_thread is running. I am running on Centos with kernel version 3.10 and libpcap version 1.5.3 I tried debugging the tcpreplay and noticed that the function is stuck on pcap_finalldevices(). this problem occurs both with RTE_KNI_PREEMPT_DEFAULT=1 and 0 but when setting to 0 it takes less time for the pcap_finalldevices() to complete. there are enough cores so the issue is not related to cpu. Is it a known issue? is there any workaround?
Thanks, Shirley.
