2014-07-08net/hsr: Use list_head (and rcu) instead of array for slave devices.Arvid Brodin1-108/+134

2014-07-08net/hsr: Move slave init to hsr_slave.c.Arvid Brodin1-137/+55
Also try to prevent some possible slave dereference race conditions. This is finalized in the next patch, which abandons the slave array in favour of a list_head list and list RCU. Signed-off-by: Arvid Brodin <arvid.brodin@alten.se> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-02-18hsr: Use ether_addr_copyJoe Perches1-5/+5
It's slightly smaller/faster for some architectures. Make sure def_multicast_addr is __aligned(2) Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-11-03net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0)Arvid Brodin1-0/+596
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). Signed-off-by: Arvid Brodin <arvid.brodin@xdin.com> Signed-off-by: David S.
