[eepro100] [eepro100]sporadic hangups

Hi All,

I'm experiencing sporadic lockups, which I've concluded are due to the 
problems covered here regarding the eepro100 chip/driver.  I was using the 
driver RedHat distributes(v1.09 w/rev.1.36 by Andrey Savochkin), and I was 
unaware of the sleep mode setting in the EEPROM.  I've changed those two 
things, and that seems to have had a positive effect, but I was wondering one 
more thing.  Below I've included the output of "mii-diag -v -D eth0", and I 
was wondering if I needed to do anything regarding the connection speed.  I 
noticed that at the end, autonegotiation had not completed, but that a link 
of some description was established.  The communication does seem to be 
happening well enough, but I'd like to avoid potential problems.  Do I need 
to force a 10BaseT connection, or is the driver handling this just fine by 
itself?  Thanks in advance.
