You are probably using some older driver and certainly not the one from 
Scyld. Your driver doesn't have support for the MII ioctl's so mii-diag 
or mii-tool would not work on it.

If you just use 'ping' without specifying a packet size, then you won't 
see many errors, because they are only 64 bytes packets sent once a 
second. If you want to get better results, use 'ping -f' as root and 
specify some large packet size (like 50000).

The first line looks bad - the driver was not able to read the MII 
registers correctly. Please check that you are using a recent driver 
version and that you are not forcing any media type with module options. 
Also, get the DOS-based tool from 3Com and check that the media/duplex 
settings are on "Auto" or "NWAY" or something similar (I don't know how 
this options look like for a 900 card).
All the other diagnostic output is bogus because it's based on these 
register values.

mii-tool uses the same registers to gather its data, so you get the same 
bogus output.
