Sorry for such a delayed review of this patch. I have bit more time
now that multithreading is in, so let's try to get this merged this
week.
Is this v4 the most recent version? Since I was so delayed reviewing
it, it no longer applies to master.
There's one major problem with this patch which
When there is no incoming data traffic at the interface for a period,
BFD decay allows the bfd session to increase the min_rx. This is
helpful in that some interfaces usually idle for long time. And cpu
consumption can be reduced by processing fewer bfd control packets.
