I don't use any update/set call to modify the reference counter, but I have
a theory about it.
Is it possible the mbufs are being accessed too fast after being set and
just before the reference counter has been updated internally?
I say so because I got a PANIC error after enabling MEMPOOL debugging. It
said 'bad ref cnt' and the dump stack pointed to rte_kni_tx_burst(), so I
thought this could be an explanation for that error.
Any ideas?

Regards,
Javier
