Hum, taking a closer look at it:
it's the if_data struct that needs to be changed. This will change the size
of struct ifnet (I doubt userland use it, execpt kmem grovelers) and
Sure, with this change, programs that use if_msghdr will need to be
recompiled (if_msghdr is used for sysctl and one routing socket message), just
like other kmem grovelers. Is has one internal use in libc, but at it's
internal it's not an issue.
Other things that need to be recompiled:

Is this a real issue ? I'm not sure versioning is straitforward in this case.
