Hi, I am facing the issue that none of the callbacks for the respective
commands in the pktgen application are being executed.
Further debug showed me that from the macro
foreach_port(_portlist, _action) from the file pktgen.h
the statement
if (info->seq_pkt == NULL) { \
continue; \
} \
_action; \
always yeilds NULL and hence repeats the loop. Due to this the statement
_action
never gets executed. Hence the callbacks for none of the commands are
invoked.
Let me know what could be the reason for info->seq_pkt to become NULL
always.
Thanks & Regards
Nagaraj Trivedi

Not sure I can debug your problem without more details, I do see info->seq_pkt being valid, is some specific commands not working or more details would be great. I need to know version of DPDK and Pktgen you are using and the console startup output plus the command line would be helpful.

Hi Keith, the version are Pktgen Ver:2.9.6(DPDK-2.3.0)
I have verified putting printf in the if statement where it checks for
whether info->seq_pkt is NULL and yes it is coming 'TRUE'
Due to this reason the continue; statement is executed and hence the
'_action' never gets executed and the respective callbacks are not
executed.
I have the captured logs for you as you have requested. Also it would be
of greater help if you can point me to the places in the code where memory
for pktgen->info->seq_pkt and where it is populated.
Below is the info you have requested

The above lines which you are seeing is the additional logs I have placed
within the foreach_ports macro. It clearly shows that for each of the
ports the info->seq_pkt is NULL and continue; statement gets executed but
_action will never be executed.

Hi Keith, it is working now.
The issue was related to core to port mapping that was not done. Corrected
command line parameters during pktgen invocation and it worked.
Thanks & Regards
