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.
