- 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), but no compliancy tests have
- been made.
- You need to perform any and all necessary tests yourself before
- relying on this code in a safety critical system!
- If unsure, say N.
