looks good to me. but there is no need to rush, especially
it will be nice if all interested parties agree on an approach
and possibly even naming.

I do not have any specific test case but the problem came up
when an interface is in netmap mode and dispatches to the
in-kernel VALE switch, and userland tries to move the interface
back to regular mode.
