Another solution would be to have a "rollover" flag which tells the
FSM to first wait for a rollover before checking the timestamp.  This
flag could be set by the host when it detects a rollover in timing.  I
don't know if the host keeps track of the last transmission time or
who would be responsible for setting the flag.  Maybe it's getting a
bit complicated?

What do you think of those ideas?  Do you have a proposed solution?

I was thinking about this problem when writing the TDMA MAC. I like the rollover flag idea much better than the assumption everything will be transmitted. It's very easy for the host to detect and set a bit like this. The host is generating the timestamps, and can easily tell something like this.

But, I'd say lets take care of the RX issue first...
