I have 2 pods running on same worker
Pod1 send to pod2

Pod2 receive with 4 bytes less at end of packet
This problem happens only if the 2 nic are on the same pf,
If different pf, the problem doesn’t occurs

I tried with dpdk21 and dpdk22
The code is using driver net_iavf
nic e810c
driver: ice
firmware-version: 4.00 0x800139bc 21.5.9
Who does the stripping? The dpdk code or the card?
Why is is different behavior for same pf and different pf ?
What should i change or check?


port_conf.rxmode.offloads |= RTE_ETH_RX_OFFLOAD_KEEP_CRC;   //Don't strip CRC
port_conf.rxmode.offloads &= pi_devInfo.rx_offload_capa;
int ret = rte_eth_dev_configure(pi_nPort, nRxQueues, nTxQueues, &port_conf);



struct rte_eth_rxconf rx_conf;
rx_conf.offloads = RTE_ETH_RX_OFFLOAD_KEEP_CRC;

            int ret = rte_eth_rx_queue_setup(
                pi_nPort,
                nQueue,
                nRxRingSize,
                socket,
                performanceMode?NULL:&rx_conf,
                pool);
