Peter Heise ee1c279772 net/hsr: Added support for HSR v1
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.

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.
