We're testing our app with this setup: PCAP --- rte_eth_rx_burst--> APP-> rte_eth_tx_burst -> ethdev I'm experiencing very low TX performance leading to massive mbuf drop while trying to send those packets over the Ethernet device. I tried running ordinary l2fwd and got the same issue with over 80-90% of packets drop. When I substitute PCAP with another ordinary Ethernet device, everything works fine. Can anyone share an idea? -- Sincerely, Yerden Zhumabekov State Technical Service Astana, KZ
