This seems to be related to netdev-afxdp's batch size bigger than
kernel's xdp batch size.
I created a patch to fix it.
https://patchwork.ozlabs.org/patch/1214397/
Could anyone take a look at this patch?
Thanks,

In connection tracking system, a connection is established if we
see packets from both directions. However, in userspace datapath's
conntrack, if we send a connection setup packet in one direction
twice, it will make the connection to be in established state.
This patch fixes the aforementioned

Hi Yiyang,
Kernel +4.0 should have v3 support.
I'm also reading this doc:
Since Python 2 support was removed in 1ca0323e7c29 ("Require Python 3 and

Moreover python3-six is not available on RHEL/CentOS7 without using EPEL

When ovsdb-server is in backup mode and connects to the active
ovsdb-server for replication, and if takes more than 5 seconds to
get the dump of the whole database, it will drop the connection
soon after as the default probe interval is 5 seconds. This
results in a snowball
