I didn't get any extensive debugging :)
Anyway, I've fixed a few more outliers and committed the patch to trunk.
It works fine for me on NetBSD and Linux
There's a few outstanding todos but they are minor
* Ideally kernels need a mechanism not to ARP announce on address
addition. (I can adjust for this NetBSD at least - does Linux have a
/proc knob?)
* The BPF code could be adjusted to iterate all active states across
all interfaces and list each xid (and chaddr IF all chaddr fit into the
space).
