[meta-freescale] imx6q: force 100 mbps network

Hi,

I'm using linux-3.0.35 on my custom hardware (uses imx6 quad) based on
sabresd platform. I'm using yocto root filesystem (this is a soft float
build).

I want to force my system to use 100 mbps ethernet speed even if the
network supports 1000 mbps link. How can I enable this ?

My custom hardware uses Micrel's Gigabit Ethernet PHY KSZ9021RNI.

I can change the network speed (by ssh-ing into the linux system) using:
ethtool -s eth0 autoneg off speed 100
but I want network speed of 100 mbps when network is initialized during
startup.

Any inputs will be of help.

-Pj
