[PATCH RFC 0/2] virtio-net: interrupt related improvements




Now that we have brought the virtio overhead way down with a fast packed
ring implementation, we seem to be actually observing TCP drops
indicative of bufferbloat. So let's try to enable TSQ.  Note: it isn't
clear that the default pacing is great for the virt usecase. It's worth
trying to play with sk_pacing_shift_update to see what happens.

For this reason, and for a more important one that I didn't
have time to test it yet, sending as an RFC.

Michael S. Tsirkin (2):
  virtio-net: bql support
  virtio_net: bulk free tx skbs
