Re: [dpdk-dev] rte_pktmbuf_alloc fails

[Meir Tseitlin <mirots@gmail.com>]

I think I found the problem - it was solved by manually calling
rte_pktmbuf_free for each packet.
It seems that rte_pktmbuf_free is not automatically called from
within rte_eth_tx_burst if packets are sent to pcap device.

Is it possible?
