Really? Did you /read/ the link I sent you?  Obviously not.  Okay, well
I'll hold your hand then.  No, you do not need to write an init script
for that.  There are VERY FEW things that need that kind of expertise to
do any more.  This has been an option for a decade at least.  Here's how
you do it:

#
# File: /etc/sysconfig/network-scripts/ifcfg-eth0
#
DEVICE=eth0
IPADDR=192.168.1.100
NETMASK=255.255.255.0
BOOTPROTO=static
ONBOOT=yes
ETHTOOL_OPTS="speed 100 duplex full autoneg off"

See the last line?  (In case you missed that part, too.) That line
passes the ethtool parms to the NIC at initialization time either at
boot (as in the case of this one) or whenever you bring the interface up.

I ask again nicely.  Google this stuff first before you ask the list.
We're hear to help /after/ you've done all the research you can do based
on your knowledge level.  We're not here to do it for you, we're here to
help you learn it for yourself.

Geez.
