netdev-dpdk: fix tso bug

when userspace tso enabled, mbuf RTE_MBUF_F_TX_TCP_SEG and RTE_MBUF_F_TX_TCP_CKSUM flag bits all positioned will result in driver hang using intel E810 vf driver iavf. As refered to dpdk csum example, RTE_MBUF_F_TX_TCP_SEG should only be positioned when tso is open. Signed-off-by: Dexia Li <[email protected]> Signed-off-by: 0-day Robot <[email protected]>
