The range check on vlan_id in register_vlan_device is off by one, and it
prevents the creation of a vlan interface for vlan ID 4095. (OSX allows
this, I checked.)

Then OSX should fix their code. 4095 is reserved.

If it's reserved, then it's up to the user to reserve it.

I actually had reason to use this to fix a misconfigured host that was
using vlan 4095. This got in my way.
