		traffic if we can help it.

		netdevsim is great, can I extend it for my out-of-tree tests?
		-------------------------------------------------------------

		No, `netdevsim` is a test vehicle solely for upstream tests.
		(Please add your tests under tools/testing/selftests/.)

		We also give no guarantees that `netdevsim` won't change in the future
		in a way which would break what would normally be considered uAPI.

		Is netdevsim considered a "user" of an API?
		-------------------------------------------

		Linux kernel has a long standing rule that no API should be added unless
		it has a real, in-tree user. Mock-ups and tests based on `netdevsim` are
		strongly encouraged when adding new APIs, but `netdevsim` in itself
		is not considered a use case/user.

		Any other tips to help ensure my net/net-next patch gets OK'd?
