I put the script under /usr/local/etc/rc.d/.  FreeBSD will attempt to 
execute any file in that directory that ends with .sh during bootup and 
shutdown.  During bootup, it will execute the file with the argument 
"start".  During shutdown, it will execute the file with the argument 

In the script's current state, ath0 is configured at bootup with a 
static IP address.  To use dhcp after bootup, root would have to 
execute the following commands:

/usr/local/etc/rc.d/ath0 stop
/usr/local/etc/rc.d/ath0 dyn

The first command would undo the static IP configuration.  The second 
command would execute dhclient per the "dyn" section of the script.

If you wanted to use dhcp at bootup, you would have to change "start)" 
to something else; and then change "dyn)" to "start)".

Please note that if your using the script for a pccard, the card needs 
to be inserted prior to bootup for configuration to occur 
automatically.  If not, "/usr/local/etc/rc.d/ath0 start" would need to 
be executed manually after bootup.

I hope this helps.
