Hi Lev,
Thanks for the update. Even with the latest added fixes and sanity
checks, the resulting code is now 30 lines shorter *and* more readable.
Some last questions / comments inline:

Now that the code is refactored, it is clear that for the tuntap case
the code will ignore any of the earlier set flags. Can you maybe add a
comment explaining why the other flags are being ignored?

Grammar nit: "there is data" (remove 'a').
Otherwise, as far as stare-at-code goes, I'm fine with this patch now. I
haven't tested it, nor have I reviewed Windows-specific interaction. So
this needs at least one other review from someone able to review those
parts.
