Intel NIC folks,

Why do the Intel network drivers, when using =
RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE, fall back to normal freeing when the =
mempool cache is empty (cache->len =3D=3D 0)? It doesn't make sense to =
me.

Example:
https://git.dpdk.org/dpdk/tree/drivers/net/intel/common/tx.h#n146

Med venlig hilsen / Kind regards,
-Morten Br=F8rup
