[dpdk-users] How to getting first objects from a rte_mempool buffer every time?

[宋捷 <songj@zctt.com>]

Hi all，

 

I have a pcap file that contained 100 IP packets. I can send them by DPDK by
below steps:

 

1.     I create a rte_mempool buffer by rte_pktmbuf_pool_create. load these
100 packets into this buffer. 

2.     call rte_mempool_get_bulk to getting packets form rte_mempool buffer
into rte_mbuf buffer,

3.     put rte_mbuf buffer into rte_eth_tx_burst for sending .

The pcap packets can be sent out from 1 to 100  Ok.

 

Now I want to send the only first 10 packets every time,

rte_mempool_get_bulk can get 1-10 objects, but next time it will get 11-20
objects.

I don’t know if there is easy way to getting first 10 objects from
rte_mempool buffer every time?

 

 

Thanks
