Hi Rami: thank you for your inputs.
Indeed, I had syntactic issues, and also, restarting the machine did the trick. One thing that I was not clear is about "portmask". For instance, in the docs, we can find "./l2fwd -n 1 -c f -- -q 8 -p 0x3". What exactly the value "0x3" refers to? Regards, Kushal.
