  Log Message:
  Support vlan-passthru for tag=0 logical switch ports

When vlan-passthru is true for LS, for untagged localnet ports, tagged
VLAN traffic originating from VIFs should be passed through intact since
the VLAN header belongs to VIF user, not the localnet port fabric.

This patch adds multinode test cases to cover scenarios where packets
traverse through fabric layer, for both tagged and untagged (tag=0)
localnet ports.
