Changes to the Digi/Arnet SYNC driver:

1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously.
   With this change the speed as tested with ttcp on a 2Mbit link went up
   from 206kbyte/s to 236kbyte/s.
2. Change the rest of the functions to also have the definition of the
   return value on a sepperate line.
3. Remove some unused variables.
4. Add code to recover from DMA underruns.
5. Reorder ar_get_packets() to handle errors better.
6. Only allocate a mbuf cluster if the data is more than the mbuf.

(and in a second diff in addition to the above)
7. Stops the occasional DMA underruns that occurred when 2 channels
   are running at 2Mbit/s.
