Subject: [dpdk-users] ovs-ofctl dump-ports shows a huge rx_bytes value when using dpdk i40e pmd driver
Date: Sun, 24 Dec 2017 06:50:25 +0000	[thread overview]
Message-ID: <A69E93D1CF6DFA4BA33FB8D8DAFFFD1902B80CA0@DGGEMI511-MBS.china.huawei.com> (raw)

Hi all, I have faced the following issue: I have a Intel X710 card, two ports on it, after adding one port to an OVS + DPDK bridge, ovs-ofctl dump-ports shows a huge rx_bytes value:
ovs-ofctl dump-ports br0
OFPST_PORT reply (xid=0x2): 3 ports
  port  2: rx pkts=0, bytes=0, drop=0, errs=0, frame=0, over=0, crc=0
           tx pkts=0, bytes=0, drop=0, errs=0, coll=0
  port  1: rx pkts=0, bytes=18446744073709551612, drop=0, errs=0, frame=0, over=0, crc=0
           tx pkts=0, bytes=0, drop=0, errs=0, coll=0
  port LOCAL: rx pkts=9, bytes=786, drop=10, errs=0, frame=0, over=0, crc=0
               tx pkts=0, bytes=0, drop=0, errs=0, coll=0

OVS version is 2.7.3, dpdk version is LTS 16.11.4, from ethtool I can see:
driver: i40e
version: 2.0.23
firmware-version: 5.05 0x80002a82 1.1313.0

Some other clues from gdb：before i40e_dev_stats_get returns, pf->stats: rx_bytes = 18446744073709551540, rx_unicast = 0, rx_multicast = 19, rx_broadcast = 0

Anybody found this issue too?
