--- Comment #1 from Alan Somers <asomers@FreeBSD.org> ---
This is from tap(4). How is it different from what you are proposing?
On the last close of the data device, the interface is brought down (as
if with “ifconfig tapN down”) and has all of its configured addresses
deleted unless the device is a VMnet device, or has IFF_LINK0 flag set.
All queued frames are thrown away. If the interface is up when the data
device is not open, output frames are thrown away rather than letting
them pile up.
