Hey,
        Scott points out that the current behaviour of draining the
entire queue in tap_send() doesn't work with non-virtio NICs because
we drop a packet when the NIC queue fills up.

        This series of patches first disables this behaviour, fixes
various aspects of the queueing logic and then re-enables the behaviour
in a way that works with all NICs.

        The first patch should also be applied to stable-0.11, I'll
follow up with a backport.

        Scott, Sven, if you could test the tap-drain-queue branch from
my tree, that would be great:

Thanks,
Mark.
