     I'd like to hear from anybody who's written device drivers that
talk to protocol implementations (like TCP/IP) running on front end 
processors.  I'm also interested in drivers that actually implement 
the protocols themselves.  In particular:
   - How difficult were these drivers to write and debug compared to,
     say, a tty device driver?
   - How big were they, again compared to something like a tty driver?
   - How difficult was the driver implementation compared to doing it
     under some other operating system?
   - And, finally, how does the complexity of a driver that implements
     the protocol compare with one that just talks to a front end
     processor running the protocol?

Thanks.
