i want send pkt by rte_eth_tx_burst , so, i build two rte_mbuf, such as:


rte_mbuf  *buf1,*buf2;


buf1 = rte_pktmbuf_alloc(...)
buf2=rte_pktmbuf_alloc(...)


buf1->next = buf2;
buf2->next = NULL;
buf1->nb_segs = 2;
buf1->data_len = 64;
buf2->data_len = 64;
buf1->pkt_len = 128;
buf2_pkt_len = 64;


rte_eth_tx_burst(portid,queueid,(rte_mbuf**)&buf1,1);


can't send this pkt where is wrong ?  thank you
