Hi
Our dpdk application uses dpdk-stable-18.11.9. It successfully receives udp
packets <1500 octets, but does not correctly process larger udp packets.
I don't know where to look. Is there a DPDK function that sets or takes the
MTU size for reception?
How would jumbo packets typically be supported on the Rx side?
Best regards
David

Did you configure larger mtu and enable jumbo in the rx_conf?

No, I hadn't done that. Working now. Thanks!
