Hi Jerin,

If I understand correctly this assumption would be made in the driver?
But then applications like l2fwd-event will break.

Agree, this is what we want to avoid.

Okay.

Thanks for suggesting this, we also thought of it, but would prefer having this as a
runtime option rather than static option.
We would not like to have one time configuration restriction.
