current-950109 NetBSD-Amiga custom ethernet if

Every other incoming icmp echo request is ignored, is this anything
known?  I just saw this and haven't really time to look at it now.
Essentially, what I am wondering, is if this could be my fault (the
ethernet driver is my own beast) or if I should look into the generic
net code.

Below, filippa is a NetBSD/Amiga being pinged from a SVR3 box: ix.

09:13:18.308095 ix.appli.se > filippa.appli.se: icmp: echo request
09:13:19.310506 ix.appli.se > filippa.appli.se: icmp: echo request
09:13:19.311098 filippa.appli.se > ix.appli.se: icmp: echo reply
09:13:20.308050 ix.appli.se > filippa.appli.se: icmp: echo request
09:13:21.310463 ix.appli.se > filippa.appli.se: icmp: echo request
09:13:21.311067 filippa.appli.se > ix.appli.se: icmp: echo reply

As you can see, the echo requests at even seconds just vanish
somewhere (or maybe the echo replies on their way out).  Ideas?
