6 hardware interfaces, `ifconfig -a` lists only 3?

[jago25_98]

answer:

It's an unmanaged switch so you only got control of 3 interfaces:

eth0 = local
eth1 = WAN
eth2 = wireless

----
I just can't figure this out.
I have 5 ethernet holes on the back of my WL500G (one of which is WLAN) and a wireless port too. But when I run ifconfig -a I only get 3 interfaces; eth0, eth1 and eth2. (sit0 is IPv6 and br0 is a bridge).

What are the other interfaces? Even if the interfaces are not turned on I expected them to show up with the -a option.
