Subject: pcap->eth low TX performance

Message-ID: <55E91AB2.4080604@sts.kz> (raw)
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?
