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
