In Linux, both HSR and PRP are implemented in the hsr driver, which
instantiates a virtual, stackable network interface with two member ports.
The driver only implements the basic roles of DANH (Doubly Attached Node
implementing HSR) and DANP (Doubly Attached Node implementing PRP); the roles
of RedBox and QuadBox are not implemented (therefore, bridging a hsr network
interface with a physical switch port does not produce the expected result).
