      net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0) · f421436a
      Arvid Brodin 提交于
      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).
