As you may know I do a lot of debugging on Pktgen and I feel they are a nuisance. I can try to see if we can clean up these messages, but do not hold your breath on getting them to be removed.

Understood, I am just providing some usability feedback from the 
community. Any cleanup, however partial it may be for other reasons, 
will personally aid me in simplicity of debugging and using the pktgen 
to find performance improvements in other community applications and 
DPDK itself, which is my true end goal here. In particular I need it for 
all the changes I posted at various points for librte_lpm so I can test 
all this stuff to make sure it really works.

DPDK's messages might not be helpful for you, but in my case, the 
temporary hostile modifications I made based on the writeup sent 
previously, in order to make these messages visible again, is what 
allowed me to find and fix the root causes of my inactive port issues, 
because I have been working with DPDK's messages since 2011 and am very 
familiar with what they mean inside DPDK itself, so they were the only 
UI of Pktgen familiar to me at all compared to the rest which is custom 
stuff I didn't use before.

I found a lot of info is being overwritten or lost due to the complex 
sequence of all these calls. This is what led to my email of questions 
for you.

OK. But do note that this convention is different from every other 
project I've coded on before.

Sincerely,
Matthew.
