   8           If you say Y here, then your Linux box will be able to act as a
   9           DANH ("Doubly attached node implementing HSR"). For this to work,
  10           your Linux box needs (at least) two physical Ethernet interfaces,
  11           and it must be connected as a node in a ring network together with
  12           other HSR capable nodes.
  13
  14           All Ethernet frames sent over the hsr device will be sent in both
  15           directions on the ring (over both slave ports), giving a redundant,
  16           instant fail-over network. Each HSR node in the ring acts like a
  17           bridge for HSR frames, but filters frames that have been forwarded
  18           earlier.
  19
  20           This code is a "best effort" to comply with the HSR standard as
  21           described in IEC 62439-3:2010 (HSRv0), but no compliancy tests have
  22           been made.
  23
  24           You need to perform any and all necessary tests yourself before
  25           relying on this code in a safety critical system!

  27           If unsure, say N.
