[dpdk-dev] pcap->eth low TX performance

[Yerden Zhumabekov]

Hello,

Did anyone try to work with pcap PMD recently? 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?
