Here is how it's called from the network script in /etc/rc.d/init.d:

ifconfig eth0 192.168.255.220 broadcast 192.168.255.255 netmask
255.255.255.0 up

ifconfig eth1 "192.168.55.320 broadcast 192.168.55.255 netmask
255.255.255.0 up

Note, I changed the ip for eth1, it was 192.168.255.320, but either way
does not work.  I can bring this nic up with 'ifconfig eth1 up', but
there's no ip associated with it when executing 'ifconfig' at that
point.
