Hi Friends,
Thanks for the reply.
This is the portion of the code where the I350 fails to send packet:
for(;;){
ret = rte_eth_tx_burst(port_ids[lcore_id], 0, m_pool,
burst_size);
if (unlikely(ret < burst_size)) {
for(j=ret;j<(burst_size-ret);j++)
{
rte_pktmbuf_free(m_pool[j]);
}
}
else
{
lcore_stats[lcore_id].tx += (uint64_t)burst_size;
}
}
all of the m_pool were allocated using
for(j=0;j<burst_size;j++)
{
m_pool[j] = rte_pktmbuf_alloc(pktmbuf_pool);
}
