Tests for cloned interfaces such as lagg and vlan have existed for a while but are not currently enabled. The entire sys/net test suite is not built and installed with the tests dist set, but even if it were, there are many test cases that are set to be skipped because they quickly panic the system. These panics are serious problems that need to be fixed and continuously tested moving forward to prevent regressions in the future.
Enable the existing sys/net tests. Missing tests for epair interfaces have been added, as well.
