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).
