• ee1c27977   net/hsr: Added support for HSR v1 ... Browse Code »

  This patch adds support for the newer version 1 of the HSR
  networking standard. Version 0 is still default and the new
  version has to be selected via iproute2.

  Main changes are in the supervision frame handling and its
  ethertype field.

• f266a683a   net/hsr: Better frame dispatch ... Browse Code »

  This patch removes the separate paths for frames coming from the outside, and
  frames sent from the HSR device, and instead makes all frames go through
  hsr_forward_skb() in hsr_forward.c. This greatly improves code readability and
  also opens up the possibility for future support of the HSR Interlink device
  that is the basis for HSR RedBoxes and HSR QuadBoxes, as well as VLAN
  compatibility.

  Other improvements:
  * A reduction in the number of times an skb is copied on machines without
  HAVE_EFFICIENT_UNALIGNED_ACCESS, which improves throughput somewhat.
  * Headers are now created using the standard eth_header(), and using the
  standard hard_header_len.
  * Each HSR slave now gets its own private skb, so slave-specific fields can be
  correctly set.

• f421436a5   net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0) ... Browse Code »

  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).
