sorry, I might have written that down wrong or read the output wrong.
I did not modify the l2fwd example.

At 1.6 GHz as it is simply too fast at 3.3 GHz ;)


I’ll probably write a minimal example that shows my
problem with tx only sometime next week.
I just used the l2fwd example to illustrate my point
with a 'builtin‘ example.
