I can confirm seeing it here also, you are not alone:

$ netstat -i
Name    Mtu Network       Address              Ipkts Ierrs Idrop    Opkts Oerrs  Coll

[..]

I had not noticed it before. I am not encountering any packet loss
or other networking problems. No idea about the reason.

This is on FreeBSD 8.1-RELEASE-p2 amd64 with GENERIC kernel.
