I started playing with HSR and run into a problem. Tested latest
upstream -rc and noticed more problems. Now it appears to work.
For testing I have a small three node setup with iperf and ping. While
iperf doesn't complain ping reports missing packets and duplicates.

One thing I didn't mention in the patches (and remember now) is that
before the revert (while looking for the reason of the duplicated
packets) I randomly observed a crash while hsr network was up but had no
traffic. It didn't happen with traffic or I was not patience enough.
It appears from the backtrace that the node was removed twice. This was
the additional boost for the revert since it appears it is not used. I
Didn't see the crash after the revert.
