This is from a SPARC Classic that I rebooted yesterday with a -current
kernel from two days ago. I am just about to reboot it again with today's
kernel, but thought I'd have a look/see at the system stats while I was at
it. This is from "netstat -i" and I'm wondering about the number of UDP
packets received, versus the number of PCB hash misses - 98.6% missed.

This machine has /usr/src NFS mounted read-only for builds against a SPARC
LX running NetBSD 1.3 on a private Ethernet. It also speaks rwhod and NTP.

What's up with all those PCB hash misses?

	curious,
