I would also prefer if it was the default behavior but after discussing
it with David, we thought it may cause issues to users who assume the
driver will receive all frames, regardless of promisc/allmulti.

I will happily submit a v2 without the opt-in flag. Users can always
enable promisc if they want to revert to the previous behavior.
