Bug In v0.89 tulip.c

[Jason Ledbetter]

I apologize in advance for the length of this message... but I wnated to
include as much information as possible. 

I'm trying to get the integrated ethernet card in my Compaq Presario 5660
working under 2.0.34. As far as I know, it is a 21143 based chipset .. at 
least according to Win98. The proc/pci output below seems to contradict
this. I compiled 2.0.34 with the latest tulip.c and below are the
results.

/proc/pci:

Bus  0, device  4, function 0:
  Ethernet controller: DEC DC21142 (rev 65).
  Medium devsel.  Fast back-to-back capable.  IRQ 5. Master Capable.
Latency=64.  Min Gnt=20.Max Lat=40.
  I/O at 0x2400.
  Non-prefetchable 32 bit memory at 0x41100000.


Below is the output from tulip-diag -f -e -a -m -m immediately after
bringing up the interface.

... now something interesting.. after 5-10 seconds, if I rerun this again,
I get the following diff'ed output.

> Transmit started, Receive started, half-duplex.
>  The transmit threshold is 128.
>  Port selection is 100mbps-SYM/PCS 100BaseTx scrambler, half-duplex.

... In addition, below is sent to console...


eth0: The transmitter stopped!  CSR5 is f0678006, CSR6 b3862002.

This stops if I plug a 10bt cable into it...

If I try to ifconfig the interface down, i get this....

Any thoughts/etc would be great...
