to filter frames in the protocol layer.

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

you may also want a firewall that has no ip address yet filters ip packets through iptables ;-)

See to http://ebtables.sourceforge.net/

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)

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

See the iptables/ebtables interaction:

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?
