The main use-case of switch NI with multiple ports is not actually to
bridge multiple L2 switches for redundancy and run STP (*) to avoid loops,
but to allow connecting external end devices (e.g. sensors) directly
into the same L2 segment as the applications running on the edge node.
With VLAN-enabled Switch NI, the user should be able to use a physical
network port attached to Switch NI as a VLAN access port (by default
all switch NI ports are configured as trunks).
(*) Regardless of the use-case, we will always run STP on a multi-port
switch NI to avoid accidental bridge loops.
