Between these two, m= y vote was librte_eal (as we already have plenty of similar items > in librte_eal/common/include) instead of librte_mbuf, as to me the packet= color is not related to how DPDK decides to pick its packet meta- > data. >=20 > To me, librte_eal/common/include is still the best option, but I guess I = can live with librte_mbuf in case Konstantin has a hard opinion on it. >=20 > What is your choice, Konstantin? If to choose between EAL and mbuf - I would choose mbuf, that what I stated in my previous mail, see above. BTW, I probably missing something, but why rte_net is not an option? What circular dependency you are talking about? Konstantin=20
