[dpdk-dev] No packets received if burst is too small in rte_eth_rx_burst

[tom.barbette at ulg.ac.be]

Hi list,

Between 2.2.0 and 16.04 (up to at least 16.07.2 if not current), with the XL710 controller I do not get any packet when calling rte_eth_rx_burst if nb_pkts is too small. I would say smaller than 32. The input rate is not big, if that helps. But It should definitely get at least one packet per second.

Any ideas? Is that a bug or expected behaviour? Could be caused by other ABI changes?

Thanks,
Tom
