Hiï¼
Thanks for your reading.
I encounter two problems when I use l2fwd and l3fwd. Here are the problemsï¼
P1. In l2fwd source codeï¼I change these valuesï¼and it do not receive packets after receiving about 1K packets.
#define NB_MBUF 81920
#define RTE_TEST_RX_DESC_DEFAULT 4032
Is it relevant with the i40e driver code below?
" rxq->rx_tail = (uint16_t)(rxq->rx_tail & (rxq->nb_rx_desc - 1));"
P2. I use l3fwd to process about 35Gps IP packet and packet length is 64B,the process drop many packets. Then I use 4 rx_queues and 4 lcores, but it's performance improves a little. The same result happens when I use 6 queues and 6 lcores. So how to location where the problem is. Is there any suggestions?
My environmentï¼
OSï¼Redhat 6.5 X86_64
CPUï¼Intel Xeon E5-2650 v3@2.3GHz
NICï¼Intel Corporation Device [8086:1580]
DPDK: 16.11
