I don't see anything wrong with the way things are. Perhaps some more
documentation is necessary, but as noted upthread this has a 20-year
history in the BSD networking stack and it's not like it's a

Yes- this may have been true for a long time - but quite a number of Unix
variants don't require it, so I forgot :-).. For example, neither OpenBSD nor
NetBSD seem to require it.
It turns out that this is only stumbled on rarely- but if it's all the same to
you, a comment would help a lot.

Oops -- this is going to be the source of a lot of confusion. By 4.2
I am referring to 4.2BSD, of course, and not FreeBSD 4.2 which would

Not only that but the ifnet structure must be the first part of the arpcom
struct so that arpcm, ifnet and softc often need to be the same.. I've
been gradually trying to remove this requirement over the last 10 years
but it's still there.. :-/
Comments can't hurt though..

This bit me in the butt yet again about FreeBSD and some assumptions about how
a NIC's softc is laid out- I don't really it stated elsewhere, so a couple
source file comments seem in order.. Frankly, this kind of assumption is
dangerous and unnecessary with methods, but at the very least it ought
