    tests: basic VLAN test
    
    Set up two jails connected by an epair. Create VLAN interfaces in both
    jails and check connectivity.
    
    This is a very basic test, but exposed panics during the network stack
    epoch work, so this is worth testing.
    
    (cherry picked from commit fcd69db27dc93796374600938e4fcf5544aa2a06)
