for example, for filtering IPX packets in an IP network.

you may also want a firewall that has no ip address yet filters ip

Who know why?... ;)
To filter ethernet frames (on link Layer), but not only an ip packets 
(on Network Layer) on Your Linux-powered bridge (because bridge is [mostly] 
Layer 2 (Linkk Layer) device)

See the iptables/ebtables interaction:

[bmcdowell]

I have two questions along this vein:

Does it offer any features over iptables for just IP users?

Does that mean (and I think it does) that without ebtables IPX traffic would pass a bridge, such as the one this list is for, uninhibited?
