# # IEC 62439-3 High-availability Seamless Redundancy # config HSR tristate "High-availability Seamless Redundancy (HSR)" ---help--- If you say Y here, then your Linux box will be able to act as a DANH ("Doubly attached node implementing HSR"). For this to work, your Linux box needs (at least) two physical Ethernet interfaces, and it must be connected as a node in a ring network together with other HSR capable nodes. All Ethernet frames sent over the hsr device will be sent in both directions on the ring (over both slave ports), giving a redundant, instant fail-over network. Each HSR node in the ring acts like a bridge for HSR frames, but filters frames that have been forwarded earlier. This code is a "best effort" to comply with the HSR standard as described in IEC 62439-3:2010 (HSRv0) and IEC 62439-3:2012 (HSRv1), but no compliancy tests have been made. Use iproute2 to select the version you desire. You need to perform any and all necessary tests yourself before relying on this code in a safety critical system!

Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer type cleanups from Thomas Gleixner: "This series does a tree wide cleanup of types related to timers/timekeeping. - Get rid of cycles_t and use a plain u64. The type is not really helpful and caused more confusion than clarity - Get rid of the ktime union. The union has become useless as we use the scalar nanoseconds storage unconditionally now. The 32bit timespec alike storage got removed due to the Y2038 limitations some time ago. That leaves the odd union access around for no reason. Clean it up. Both changes have been done with coccinelle and a small amount of manual mopping up" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: ktime: Get rid of ktime_equal() ktime: Cleanup ktime_set() usage ktime: Get rid of the union clocksource: Use a plain u64 instead of cycle_t
