arge1 on TL WDR3600

[Piotr Kubaj]

Thanks Adrian, that also helped me with my 1043ND. At first I thought 
that since arge0 works for LAN, arge1 must be WAN, but reading your 
email made me realize I was wrong. I think you should put this into wiki 
(that arge1 may be a dumb NIC and how to configure embedded switch to 
use the WAN port).

Also, it would be quite useful to have some way of automatically loading 
etherswitch configuration at boot time. For now the only way is to use 
rc.local. I know that your scripts make it possible, but with stock 
FreeBSD (which is what I use on my 1043ND for now) it's not really possible.
