my enviroment:
NIC:X540
DPDK version:2.2.0
problems:
start dpdk app with traffic not stopped，app can't receive any packet
from dpdk ixgbe driver (1.2w pps udp packet).
test five times would happens 1 ~ 2 times.
The stats of the nic (ipackets==3230 and imissed == ierrors):
ipackets 3230 imissed 9780225 ierrors 9780225
ipackets 3230 imissed 9792154 ierrors 9792154

The value of register RDH:1023
The value of register RDT:959
there are some desc value log for one queue, the format of the log is

other desc in the ring is all zero。
is there a bug?
PS: it was normal with linux ixgbe driver。

The rx function used was ixgbe_recv_pkts_bulk_alloc.
the problem seems that the rx desc ring not full, but nic don't write
data to ring and inc the missed error counter.

The issue can be reproduced with example program l2fwd by modifying it
to sleep 1 second before launching thread.
code like this:
....
check_all_ports_link_status(nb_ports, l2fwd_enabled_port_mask);
sleep(1);
/* launch per-lcore init on every lcore */
rte_eal_mp_remote_launch(l2fwd_launch_one_lcore, NULL, CALL_MASTER);
RTE_LCORE_FOREACH_SLAVE(lcore_id) {
if (rte_eal_wait_lcore(lcore_id) < 0)
return -1;
}
....

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.
