There are currently no kernel tests that verify the effect of setting the enabled team driver option. In a followup patch, there will be changes to this option, so it will be important to make sure it still behaves as it does now. The test verifies that tcp continues to work across two different team devices in separate network namespaces, even when member links are manually disabled.

# These tests verify the basic failover capability of the team driver via the

# `enabled` team driver option across different team driver modes. This does not
