[dpdk-dev] DPDK pktgen

[Jun Han]

Hi

I have a quick question about using your DPDK pktgen. I want to
sequentially increase the destination IP address so I modified the .lua
file in the following way. However, as I am printing the contents of IP
header in the other machine, I find that the IP address does not keep
incrementing all the way to 255.255.255.0 but quickly rolls back to some
other IP address. (e.g., from 5.54.0 to 0.1.180.0, or from 0.1.145.0 to
0.6.24.0 as shown below in bold fonts.) Do you know what could be the
problem? Am I implementing this lua file incorrectly? Thank you.

----- Part of .lua file ----

pktgen.set("0", "size", 64);

pktgen.dst_ip("0", "start", "0.0.0.0");

pktgen.dst_ip("0", "inc", "0.0.1.0");

pktgen.dst_ip("0", "min", "0.0.0.0");

pktgen.dst_ip("0", "max", "10.255.255.255");
