If mbuf is attached to an external buffer, its ol_flags will have EXT_ATTACHED_MBUF set. Without enabling/using the feature, everything remains same. If PMD delivers Rx packets with non-direct mbuf, ol_flags should not be overwritten. For mlx5 PMD, if Multi-Packet RQ is enabled, Rx packets could be carried with externally attached mbufs.
