This patch adds support for the newer version 1 of the HSR networking standard. Version 0 is still default and the new version has to be selected via iproute2. Main changes are in the supervision frame handling and its ethertype field. Signed-off-by: Peter Heise <peter.heise@airbus.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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!
|
|
|
|
If unsure, say N.
