Bah.  That DEVINET_SYSCTL_ENTRY requires having a binary sysctl
assigned, just to use as an index.

Which of course trips over all of the fine checks in sysctl_check.c to
keep people from assigning new binary sysctls by accident.

That is the only place in the kernel where he have that problem, I wonder
how much work it will be to finish untangling.
