You are doing a copy of l2fwd example to add event mode.
It was the decision from the techboard to not complicate the original
l2fwd. But it makes me nervous to see some code duplicated,
especially if you plan to do the same for l3fwd and ipsec-secgw.
We are not going to duplicate every examples. We should re-consider.

If there is only one user, making it grow in the application looks to be
the best thing to do.
Should we use it in more applications before it is more mature?
If not, we could move the code in eventdev library when we will
use it in more examples.

If we really want to have this library standalone in examples,
I suggest to give it a name and not use a "common" directory.
