Subject: Re: [PATCH v6] net/hsr: Add support for the High-availability
 Seamless Redundancy protocol (HSRv0)

From: Arvid Brodin <>
Date: Wed, 30 Oct 2013 21:10:47 +0100

> 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).
