I saw that in order to work in a VIRTIO mode I need to update the txq_flags= (part of the rte_eth_txconf structure) as follows: .txq_flags =3D ETH_TXQ_FLAGS_NOMULTSEGS | ETH_TXQ_FLAGS_NOOFFLOADS In pass - through however, this parameter should remain 0 (default value). = Apparently I need to update this parameter in runtime. Is there any flag th= at can give me any indication on a mode I am running in. Thank you, Yan
