[dpdk-users] When do we get non-contiguous mbufs from rte_eth_rx_burst?

2017-02-09 Thread Lazarenko, Vlad (WorldQuant)
Hey everyone, Does anyone happen to know if it is possible to receive non-contiguous mbufs from rte_eth_rx_burst? If so, when would this happen? I am thinking that NICs with LSO enabled could possibly do this if data does not fit into RTE_MBUF_DEFAULT_BUF_SIZE? But if the packet fits, I don't
