When I upgrade ovs kernel module from 2.9.0 to 2.10.0, then use iperf3 send
packets from a vpc vm to a vlan vm, the bandwidth decrease from 3Gbits/sec
download to 1Gbits/sec. I 

reset the commit to the first commit of erspan, then the bandwidth will
normal. Also, when the ovs module is 2.9.0, I can capture packet in
geneve_sys_6081 port use tcpdump . When upgrade to 2.10.0, 

the tcpdump can't capture any packet in the port. Does anyone know why.



Thank you,
