throttling token bucket
...bout throttling a token bucket.
As far as i understand, if there not enough tokens to dequeue a packet from
the queue, a watchdog timer will be started and the TCQ_F_THROTTLED flag will
be set. But what exactly are the consequences of setting this flag. As far
as i can see, it neither prevents the enqeueing nor the deqeueing of packets
in both functions of the token bucket implementation. I think, dequeuing of
packets will not be possible, if there are not enough tokens available.
So, what is the throttling good for?

[PATCH v2 0/3] virtio_net: Better low memory handling.

The following series changes the low memory paths in virtio_net to not
