Did you set the maximum lengths for the output queue and the driver
queue in the attach function?

I think so. :)

I beginning to think the ARP issue is a symptom not the cause. The cause
may well be something is wrong with my initialisation of the output
queue and my handling of the de-queueing packets. I've looked at many
if_* drivers sources and they all seem very similar to what I've already
done.
