We can try to test for Multi-segs in pktgen in the file app/pktgen-port-cfg.c
you can search for MULTI_SEGS and
mlx5 is referencing the mlx4 library for some reason and when you added
the mlx5 PMD it also needed the mlx4.
BTW, notice the error message states "EAL: libmlx4.so.1: cannot open shared
object file: No such file or directory” EAL Is DPDK initialization not Pktgen.

You should pick a lcore that is on the same socket as the NIC (socket 0). It
appears that lcore 1 is on socket 1. Please use the cpu_layout.py script in the
DPDK tools directory to determine which lcores to use.

You can edit the packet in the function below, but you have to do that action
everytime. Freeing the mbuf I sok, you can look into the refcnt value in the
mbuf if you want tx_burst to not free the packet completely.

Sorry, none of the questions below are supported. You can have multiple ports

I am going to guess you are using DPDK master HEAD and Pktgen master HEAD, a
number of changes are going on in
d a UDP frame to KNI interface and
see if the problem still exists does seem like a reasonable direction to
eliminate possible problems.
Beyond that I can not help, take my suggestions as you see fit.

I have been playing with uncrustify http://uncrustify.sourceforge.net/ and

The configuration file located here
https://github.com/pktgen/uncrustify-dpdk.git seems to get close the right

Does the build work without sed command, if it does then something is wrong
with the sed command. In your case just edit the new config file and enable
PCAP PMD if this

Do not know if this will help at all. I some times copy the
config/deconfig_x86_64-native-linuxapp-gcc to
config/deconfig_x86_64-mine-linuxapp-gcc then
Sorry, you must have replied to my screwup not sending the reply in pure text

comments inline below. All emails to the list must be in ‘text' format not
‘Rich Text’ format :-(

Stupid email program I tell it to reply in the format as received (text format)
and it still sends in rich text format :-(
hope this is more readable.

non-zero return for the call just means no mbufs in the pool, but that can
happen if the TX ring is larger then the number of mbufs or they are not
getting freed in the PMD or in pktgen.
Could have mbuf leak in Pktgen but I do not think so.
I will try your suggest for the lastest 18.08 rele
d have a
problem as it does not work in testpmd and pktgen. To me this is not a pktgen
problem but a problem with something else.
The only other thing I can suggest is trying the latest 18.08 release for
pktgen and see if that works.

k is not up or is going up and down. If you can loop the cable back
to the same machine to a different port (if you have two ports).
