hi all,
In "testpmd", the default nb_pkt_per_burst value is 16, that is, receive 16 packets one time and then forward. Now, I set nb_pkt_per_burst=1, and after the packet received, delay 50us, because I have to add some packet processing steps between receive and transmit. However, in this situation, I lost 20% packets. How could this happen? And what should I do to have an effect? Any help will be appreciated. Best Regards. Maria
