I got a usb nic, one you can by in the Apple store, or possibly cheaper on line.
It's white, small and neat, but does get a little warm, won't be putting it in natural position on top of dockstar.
I bears the Apple code MB442Z/A
To get it to work-
modprobe asix
ifconfig -a to see it
ifconfig eth1 xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx
and would go in /etc/rc.conf as
MODULES=(asix)
INTERFACES=(eth0 eth1)
eth1="eth1 xx.xx.xx.xx netmask xx.xx.xx.xx broadcast xx.xx.xx.xx"
or
eth1="dhcp"
and possibly edit
gateway="default gw xx.xx.xx.xx"
