Jon Paul Maloy 40501f90ed tipc: don't reset stale broadcast send link ... When the broadcast send link after 100 attempts has failed to transfer a packet to all peers, we consider it stale, and reset it. Thereafter it needs to re-synchronize with the peers, something currently done by just resetting and re-establishing all links to all peers. This has turned out to be overkill, with potentially unwanted consequences for the remaining cluster. A closer analysis reveals that this can be done much simpler. When this kind of failure happens, for reasons that may lie outside the TIPC protocol, it is typically only one peer which is failing to receive and acknowledge packets. It is hence sufficient to identify and reset the links only to that peer to resolve the situation, without having to reset the broadcast link at all. This solution entails a much lower risk of negative consequences for the own node as well as for the overall cluster. We implement this change in this commit.
