Sorry for resubmission,
Still I am stuck at receiving any packet more than 1500+bytes. is it related to
driver?I can send packet larger than 1500bytes so I am not suspecting anything
wrong with my mbuf initialization.
In my application I am using following code...
#define MBUF_CACHE_SIZE 128#define MBUF_DATA_SIZE
RTE_MBUF_DEFAULT_BUF_SIZE#define JUMBO_FRAME_MAX_SIZE 0x2600 //(9728 bytes)
.rxmode = { .mq_mode = ETH_MQ_RX_VMDQ_ONLY, .split_hdr_size = 0,
.header_split = 0, /**< Header Split disabled */ .hw_ip_checksum = 0, /**< IP
checksum offload disabled */ .hw_vlan_filter = 0, /**< VLAN filtering disabled
*/ .hw_vlan_strip = 1, /**< VLAN strip enabled. */ .jumbo_frame = 1, /**<
Jumbo Frame Support enabled */ .hw_strip_crc = 1, /**< CRC stripped by
hardware */ .enable_scatter = 1, //required for jumbofram + 1500.
.max_rx_pkt_len = JUMBO_FRAME_MAX_SIZE,//ETHER_MAX_LEN },
create_mbuf_pool(valid_num_ports, rte_lcore_count() - 1, MBUF_DATA_SIZE,
MAX_QUEUES, RTE_TEST_RX_DESC_DEFAULT, MBUF_CACHE_SIZE);
I am also calling rte_eth_dev_set_mtu, to set MTU 9000, and verified with
rte_eth_dev_get_mtu.
Below is my system info / logs from dpdk (17.05.1).
Yours help is really appreciated.
Thanks.DM.
