my enviroment:
NIC:X540
DPDK version:2.2.0
problems:

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

The value of register RDT:959
there are some desc value log for one queue, the format of the log is
[desc_idx](DD value, vlan, length, status_error) :
