Well, there are plenty there on my sis0 interface (internal).

What are collisions in this context?

Traditional ethernet collisions aren't possible on modern hardware,
since there's never more than one output writing to each twisted-pair.

netstat -i on my desktop PC shows collisions on the ppp tun0
interface. I haven't a clue what that means.
