Config:
- ovs version 2.13
- dpdk version: 19.11.10
- NIC: e1000
- operation system: ubuntu 18.01
Analyze:
When I send OFPPortStatsRequest() to ovs, I get a error from struct.uppack_from(). After analyzed, I found that the reason is in fucntion OFPPropCommonExperimenter4ByteData.parser() at ofproto_v1_4_parse.py:939, which unpack message by 4 bytes but dpdk-type portstatsreply message is not a multiple of 4.
