With Pravin's last feedback I think we can do the lwt probe on init as
well.
== On startup/init ==
create an ovs_geneve interface using rtnetlink
if successful {
check parameters of the created interface
if it is lwtunnel {
set lwt flag
}
delete the created interface
set out_of_tree flag
}
== On interface creation ==
if not out-of-tree and is lwt {
create lwtunnel geneve interface using rtnetlink
if successful {
done, exit
}
}
create geneve interface using genetlink
if successful {
done
} else {
fail
}
