it seems that set fdir port conf cause the problem,just add fdir conf
in the port_conf, don't add any fdir rules.
set port conf like this in the l2fwd code.
static const struct rte_eth_conf port_conf = {
.rxmode = {
.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 */
.jumbo_frame = 0, /**< Jumbo Frame Support disabled */
.hw_strip_crc = 0, /**< CRC stripped by hardware */
},
.txmode = {
.mq_mode = ETH_MQ_TX_NONE,
},
.fdir_conf = {
.mode = RTE_FDIR_MODE_PERFECT,
.pballoc = RTE_FDIR_PBALLOC_64K,
.status = RTE_FDIR_REPORT_STATUS,
.mask = {
.vlan_tci_mask = 0x0,
.ipv4_mask = {
.src_ip = 0x0,
.dst_ip = 0xFFFFFFFF,
},
.ipv6_mask = {
.src_ip = {0x0, 0x0, 0x0, 0x0},
.dst_ip = {0xFFFFFFFF, 0xFFFFFFFF, 0xFFFFFFFF, 0xFFFFFFFF},
},
.src_port_mask = 0x0,
.dst_port_mask = 0x0,
.mac_addr_byte_mask = 0xFF,
.tunnel_type_mask = 0x0,
.tunnel_id_mask = 0x0,
},
.drop_queue = 0,
},
}
if there is no fdir conf, the program at this test case was normal.
