Bit Off-Topic: Ethernet Debugging Impossible?

[Dan "Effugas" Kaminsky]

Heh.

While trying to debug Samba packets, I noted that I had no way under Linux
to debug what kind of bad packets my Linux machine was recieving.  Some hops
through the network source showed some debug information, but not much.

Is there no way under linux to detect, say, collisions/CRC errors/etc on the
ethernet interface?
