We have been experimenting with the below:

We are trying to simply send the string "hello_there" from one machine
to another. We observe two things:
1) When the message gets to the receiver it is of correct length (11
bytes in this case) but it contains garbage.
2) The round trip message latency is coming in at about 6000 usec, or
about 100x slower than generic DEC TULIP driver with a 4 byte TCP
message round trip.
3) Entire system seems fragile and we see frequent crashes.
4) What can be done with RT_TULIP driver that can't be done with "tc"
command and network QoS support such as CBQ queue discipline, etc.?
Has this RT_TULIP worked for anyone? Is there anyone around that knows
about this code or is this an old, dormant project.
