Ilya:
- you might have more completions than descriptors available
- partial descriptor chains are a problem for hardware because you might have
to read a bunch of conscriptors twice
- how would you do deal with a big buffer that cointains a large number of
small packets with respect to completions?
- is one bit for completion enough? right now it means descriptor was actually
used. how to we signal when it was completed?
- concerned about not being able to do scatte...
