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?
