Hi everyone,

I am having a high rate of collisions on a remote Cobalt Raq3i that I host a
bunch of sites on.  Specifically this is what I am seeing (along w/ about 0 to
2% packet loss):

eth0 Link encap:Ethernet  HWaddr 00:10:E0:01:D1:B3
     inet addr:209.132.85.174  Bcast:209.132.85.175  Mask:255.255.255.252
     UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
     RX packets:44736945 errors:0 dropped:0 overruns:0 frame:0
     TX packets:49962335 errors:0 dropped:0 overruns:0 carrier:0
     collisions:2495529 txqueuelen:100
     Interrupt:11 Base address:0x1100

I recently d/l'ed an tried the Linux ethernet diag tool from:
http://www.scyld.com/diag/.  I was unsuccessful in getting any data from the
adapter (eepro100).  Here is the output from the eepro100-diag program:

  --------------------------------------------
  root at blip~$ ./eepro100-diag -f -a
  eepro100-diag.c:v2.05 6/13/2001 Donald Becker (becker at scyld.com)
   http://www.scyld.com/diag/index.html
  Index #1: Found a Intel 82559ER EtherExpressPro/100+ adapter at 0x1100.
  i82557 chip registers at 0x1100:
    0c000050 0f26c0e4 00000000 00080002 18050000 000000f0
    No interrupt sources are pending.
     The transmit unit state is 'Suspended'.
     The receive unit state is 'Ready'.
    This status is normal for an activated but idle interface.
   The Command register has an unprocessed command 0c00(?!).

  root at blip~$ ./eepro100-diag -f -e
  eepro100-diag.c:v2.05 6/13/2001 Donald Becker (becker at scyld.com)
   http://www.scyld.com/diag/index.html
  Index #1: Found a Intel 82559ER EtherExpressPro/100+ adapter at 0x1100.
  Intel EtherExpress Pro 10/100 EEPROM contents:
    Station address 00:10:E0:01:D1:B3.
    Receiver lock-up bug exists. (The driver work-around *is* implemented.)
    Board assembly 000000-000, Physical connectors present:
    Primary interface chip None PHY #0.
  --------------------------------------------

Is there another way to detect the driver settings (Full/Half, etc)?

What, if anything, can I do to debug and reduce the collisions?  Is the
multicast setting possibly causing this? 

-Jim P.
