This property allows the user to optionally configure
an interlink name on a HSR interface, so that it could
serve as RedBox (Redundant Box) by connecting DAN (dual
attachment node) to SAN (single attachment node).
This property allows the user to set the protocol
version when using HSR. Currently, the property
supports two values - `2010` (referred to as HSRv0
in the kernel), and `2012` (HSRv1).
The supervision address is read-only. It is constructed by kernel and
only the last byte can be modified by setting the multicast-spec as
documented indeed.
As 1.46 was not released yet, we still can drop the whole API for this
setting property. We are keeping the NMDeviceHsr property as it is a
nice to have for reading it.

Fixes: 5426bdf4a1 ('HSR: add support to HSR/PRP interface')
This patch add support to HSR/PRP interface. Please notice that PRP
driver is represented as HSR too. They are different drivers but on
kernel they are integrated together.
HSR/PRP is a network protocol standard for Ethernet that provides
seamless failover against failure of any network component. It intends
to be transparent to the application. These protocols are useful for
applications that request high availability and short switchover time
e.g electrical substation or high power inverters.
