It's a simple set of 'ndd' settings to get it hard-coded to 100 full. 
Here is an example of both a hme and a qfe card....

#Settings for hme0
ndd -set /dev/hme instance 0
ndd -set /dev/hme adv_100fdx_cap 1
ndd -set /dev/hme adv_10fdx_cap 0
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_autoneg_cap 0

#Settings for qfe1
ndd -set /dev/qfe instance 1
ndd -set /dev/qfe adv_100fdx_cap 1
ndd -set /dev/qfe adv_10fdx_cap 0
ndd -set /dev/qfe adv_10hdx_cap 0
ndd -set /dev/qfe adv_100hdx_cap 0
ndd -set /dev/qfe adv_autoneg_cap 0

        These will be lost upon reboot, so you will want to put it in an rc 
script to be run at boot.
