This is not accurate. Please write it after OVS' description of it, on ovs-fields.7 (not saying to copy it): inv (0x10) The state is invalid, meaning that the connection tracker couldn’t iden‐ tify the connection. This flag is a catch-all for problems in the connec‐ tion or the connection tracker, such as: • L3/L4 protocol handler is not loaded/unavailable. With the Linux kernel datapath, this may mean that the nf_conntrack_ipv4 or nf_conntrack_ipv6 modules are not loaded. • L3/L4 protocol handler determines that the packet is malformed. • Packets are unexpected length for protocol. Something like: The packet couldn't be associated to a connection. > +.TP > Example: +trk+est > .RE > .TP Thanks, Marcelo
