Hi, I have a DPDK application with two interfaces acting as a load balancer. On one of the interfaces, I am allocating a KNI interface so that certain packets can be processed by the kernel. To test I have a DHCP server connected to the physical port to which KNI is bound.
I'm having 3 issues: 1. kni_config_network_interface function set on the rte_kni_ops struct when allocating the port is called multiple times when run "ifconfig vEth0 up". This function is called 2 or 3 times every time. 2. After I receive DHCP, when I ping google.com to test, I get multiple packets that are duplicates, which are repeats of the same ICMP Sequence and with message "DUP!" attached (http://unix.stackexchange.com/a/13256) 3. After a while of running the interface KNI and using it process packets, usually after transmitting 200-300 Pings, the interface "dies out" and stops reading or sending packets to the kernel. The statistics for ping: --- google.com ping statistics --- 302 packets transmitted, 198 received, +95 duplicates, +49 errors, 34% packet loss, time 310119ms
