I was away for about 10 days, sorry for the late reply...

This is expected when using a hub.

This looks very strange...

... and this is the reason. All media related operations would probably
fail to work because of this. We've seen situations where te MII registers
would look bogus when the default media in EEPROM was set to something
else than auto/NWAY while the driver was trying to autonegotiate, so 
normally I would suggest trying to set up the default media in EEPROM to 
auto/NWAY, but I checked the EEPROM dumps that you've sent and they seem 
fine... I might not hurt though to use vortex-diag and/or the DOS tool 
provided by 3Com to check/set this.
This might also be an issue related to power management, but I don't know 
how that can be checked.
In summary, I have no idea about what can be done here, obviously if the 
driver gets wrong data from the hardware it will behave badly...

History indicates that people can't be bothered to look up a documentation 
page or this list's archives to look for answers when the card/driver 
doesn't behave propely.
