tulip v0.90q with Linksys 10/100 LAN Card (LNE100TX)

[Christopher C. Chen]

Set debug=3 for tulip and did some experiments ...

1. I slowed the send rate down to 1 frame every 5 sec
   from both ends (1,842,200 bits every 5 sec, each way).
   Things worked fine.

2. I am sending/reading a large chunk of data in a single socket 
   read()/write() call. I don't know much about the ethernet 
   frame size.  Would it help if I send them in a smaller 
   chunks?  Please see #3.

3. I set tulip debug=3 and captured the following dmesg:

   eventually.  dmesg is shown below (the buffer is wrapped).
