It's NetworkManager doing that to you.

Is there a reason they've set that up as fixed? Is there an autoneg
issue with the switch (some don't do autonegotiation correctly).

Yet another issue with NM. It doesn't give you the ability to run any
special "ethtool" stuff.

This is a wild-assed guess, but you could try editing the
"/etc/sysconfig/network-scripts/network-functions" file. Find the
"check_ethtool()" function (around line 256 or so). Add a line (marked
by "ADD--->") as shown below:
check_ethtool ()
{
[ -x /sbin/ethtool ] || return 2
ADD---> LC_ALL=C ethtool -s $1 speed 100 duplex full autoneg off
output=$(LC_ALL=C ethtool $1 2>&1)
echo $output | LC_ALL=C grep -q "Link detected: yes" && return 1
echo $output | LC_ALL=C grep -q "Link detected: no" && return 0 ||
return 2
}
It's a butt-ugly hack, but may serve your purpose.
