[Cse461] Fishnet 3 - buffering out-of-order packets

I just learned that there has been a lot of confusion about whether the
Fishnet 3 assignment requires the receiver to buffer packets that are
received out of order.

The protocol as described does NOT require you to do this. (And we won't
require it either.) You may instead discard packets that are not the next
packet expected. This will hurt performance when packets arrive late, but
with our sliding window protocol it has little effect when packets are
actually lost. And it is much simpler to implement.

If you want to implement out-of-order packet buffering, I recommend
implementing the "discard" solution first, just to get something working.

Cheers,
Janet
