    net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0) · f421436a
    Arvid Brodin authored
    High-availability Seamless Redundancy ("HSR") provides instant failover
    redundancy for Ethernet networks. It requires a special network topology where
    all nodes are connected in a ring (each node having two physical network
    interfaces). It is suited for applications that demand high availability and
    very short reaction time.
    
    HSR acts on the Ethernet layer, using a registered Ethernet protocol type to
    send special HSR frames in both directions over the ring. The driver creates
    virtual network interfaces that can be used just like any ordinary Linux
    network interface, for IP/TCP/UDP traffic etc. All nodes in the network ring
    must be HSR capable.
    
    This code is a "best effort" to comply with the HSR standard as described in
    IEC 62439-3:2010 (HSRv0).
