It depends which utility "works" on your system.
On some older 10/100 MBit interfaced rackmount systems we manage
ethtool doesn't report anything and mii-tool reports link status
accurately.
On newer boxes with GBit interfaces mii-tool reports 100 MBit link
speed for links which ethtool reports 1000 MBit and that is the actual
speed of the interfaces.
Read the man page for ethtool and mii-tool or Google for how to
actually "fix" interface speeds.

If I remember rightly sometimes it can be done when loading the driver
from /etc/modules.conf / /etc/conf.modules , other times you might
have to do it somewhere like /etc/rc.d/rc.local using
mii-tool/ethtool.
