Hi All,
This is Monika.
I am new to DPDK.
I just installed DPDK release - 18.05 on my server and trying to run
"testpmd"
Here is my command and its output :-
sudo testpmd -l 8 -n 4 -c 0x3 --socket-mem=512,512

I tried selecting different number of hugepages from 1024-10, but getting
the same initialization error.
Can someone please suggest some resolution.
Appreciate some advice.

Monika
