I have an application that generates IP traffic but whenever I try to set this flag on (*m->ol_flags = PKT_TX_IP_CKSUM)* the rte_mbuf nothing is sent out. Retrieving that statistics from the ethernet device show zero for opackets and oerrors. I'm using ixgbe driver and DPDK 1.5.0-8 (from Intel) distribution. Thanks, Daniel
