Just to clarify:
1) Most of these commands can be achieved through other ovn-nbctl commands
[e.g
"ovn-nbctl create Logical_router .." will do the same thing as what
"ovn-nbctl lrouter-add" does.
But the same is true for other existing commands like "ovn-nbctl
lport-add". These commands are
added as "shortcuts" to achieve the same thing as what the longer
version of the commands do.
2) Commands like "set-enabled" or "get-enabled" on a logical router port
are added just to add a shortcut
to be able to get/set the field in database, such commands are added
for all the fields in that table as a
matter of fact. They were not added with some specific requirement in
mind.
3) I am working on adding some test cases for the commands I added, will
submit it as soon as they are ready.
Thanks,
Nirapada
