Under Debian or Ubuntu Linux just create a script as follows:

# nano /etc/init.d/100Mbs

OR
$ sudo nano /etc/init.d/100Mbs

Append following lines:
#!/bin/sh
ETHTOOL="/sbin/ethtool"
DEV="eth0"
SPEED="100 duplex full"
case "$1" in
start)
echo -n "Setting eth0 speed 100 duplex full...";
$ETHTOOL -s $DEV speed $SPEED;
echo " done.";;

;;
esac
exit 0
Save and close the file. Setup executable permission:
# chmod +x /etc/init.d/100Mbs
OR
$ sudo chmod +x /etc/init.d/100Mbs
