We do not always provide full binary compat for ioctls (we usually try, but
sometimes it gets tricky).

Off hand I am not sure if this instance is worth fixing (or what effort
it would take).

A simple way around it is (while still running the old kernel) to extract
the netbsd-9 rescue set, e.g. to /rescue-9 and then before rebooting
into the netbsd-9 kernel move /sbin/ifconfig to /sbin/ifconfig.old and
hard link /rescue-9/ifconfig to /sbin/ifconfig.
