[PATCH net 0/2] hsr: Send correct HSRv0 supervision frames

[Felix Maurer <fmaurer@redhat.com>]

Hangbin recently reported that the hsr selftests were failing and noted
that the entries in the node table were not merged, i.e., had
00:00:00:00:00:00 as MacAddressB forever [1].

This failure only occured with HSRv0 because it was not sending
supervision frames anymore. While debugging this I found that we were
not really following the HSRv0 standard for the supervision frames we
sent, so I additionally made a few changes to get closer to the standard
and restore a more correct behavior we had a while ago.

The selftests can still fail because they take a while and run into the
timeout. I did not include a change of the timeout because I have more
improvements to the selftests mostly ready that change the test duration
but are net-next material.
