Hi,

I am trying to do some tests with Open vSwitch with DPDK,
I follow the INSTALL.DPDK.md documentation.
It is launching but a lot of packets are going to error.

 ./ovs-ofctl dump-ports br0
OFPST_PORT reply (xid=0x2): 3 ports
  port  1: rx pkts=490360, bytes=32363760, drop=0, errs=588615412, frame=0,
over=0, crc=0
           tx pkts=490360, bytes=32363760, drop=0, errs=0, coll=0
  port LOCAL: rx pkts=0, bytes=0, drop=0, errs=0, frame=0, over=0, crc=0
           tx pkts=22272, bytes=1380864, drop=0, errs=0, coll=0
  port  2: rx pkts=490360, bytes=32363760, drop=0, errs=588615412, frame=0,
over=0, crc=0
           tx pkts=490360, bytes=32363760, drop=0, errs=0, coll=0


 ./ovs-vsctl get Interface dpdk0 statistics
{collisions=0, rx_bytes=32846088, rx_crc_err=0, rx_dropped=0,
rx_errors=588615412, rx_frame_err=0, rx_over_err=0, rx_packets=497668,
tx_bytes=40155390, tx_dropped=0, tx_errors=0, tx_packets=608415}

./ovs-vsctl get Interface dpdk1 statistics
{collisions=0, rx_bytes=40155390, rx_crc_err=0, rx_dropped=0,
rx_errors=588746330, rx_frame_err=0, rx_over_err=0, rx_packets=608415,
tx_bytes=32846088, tx_dropped=0, tx_errors=0, tx_packets=497668}

DEBUG options are activated and I see the following message :
PMD: ixgbe_recv_pkts(): port_id=0 queue_id=0 rx_id=954
ext_err_stat=0x00000043 pkt_len=66

The distribution used is Ubuntu 14.04
It is a phy-phy test with an Ixia 10 Gbps .

Do you have an idea of the problem's origin ?

Thanks and Regards,

Adrian
