ftfw: fix race condition in the helloing routine
This patch fixes a race condition that can prevent one node from sending the initial hello message required to reset the sequence tracking. node A node B | | start | | hello msg |----------------------->| stop | | start | | |<-----------------------| hello-back msg In the picture above, the node A never sends the hello messages. Thus, the node B drops the next messages as they are in the before boundary. This patch adds a new state to the the helloing state-machine to fix this problem.
