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.
