[tulip] problems with ADMtek device

[Gero Zylka]

Hi,

since upgrading from a 10Mbps to a 100Mbps hup I've got problems
with my network device under Linux. I guess the problem is caused
by an incompatibility between network device (still running at
10 Mbps/half_duplex) and the hup (running at 100Mbps, full_duplex).

Here are the facts:
The network device of my linux box hangs once a day with a transmitter
timeout problem:

Feb  4 22:53:06 scream kernel: eth0: Transmit timed out, status fc264010, CSR12
00000000, resetting...
Feb  4 22:53:41 scream last message repeated 7 times
Feb  4 22:54:46 scream last message repeated 13 times
Feb  4 22:55:51 scream last message repeated 13 times
Feb  4 22:56:56 scream last message repeated 13 times
Feb  4 22:57:31 scream last message repeated 7 times


Also, I detected a lot of carrier problems and network collisions:

eth0      Link encap:Ethernet  HWaddr 00:03:6D:1A:54:C8
          inet addr:64.14.244.136  Bcast:64.14.244.143  Mask:255.255.255.240
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:256152 errors:0 dropped:0 overruns:0 frame:0
          TX packets:248160 errors:1508 dropped:0 overruns:0 carrier:1508
          collisions:5626 txqueuelen:100
          Interrupt:7 Base address:0x2000


The problem is that I dont know how to switch my network card to
100Mbps full_duplex.

Using the mii_diag tool I get the following output:

For the case that this info helps too:
